Cuno Filter Housing

• The filter housing features an entirely covered depth-cartridge filtration, which has fast and easy cartridge change-out.
• The material of construction –the materials range from several types of plastic to stainless steel alloys.

But you have to note that a suitable housing material is one that is compatible with your filtration media to avoid break down.

Nevertheless, stainless steel is the most excellent material.

The Cuno filters have a particular mirror finish sanitary 316L stainless steel structure.

• Configurable inlet and outlet nozzles: the nozzles are available in types one to fifteen. The specific positions of the nozzles permit setup for any filter system.

Even better, you can rotate and switch the nozzles to cater to your preferences.

• Accommodation of multiple houses: The Cuno filters can comfortably contain about one to four cartridges of 8 inches, 12 inches, or 16 inches.
• The filters come with integral sanitary vent and outlet check valve.
• Cunofilters have a specific spring-loaded cartridge sealing technique.
• It enhances the in situ testing of the filter system.
• The housing features a user-friendly vertical design with an inclusive Tri-Clover connection.

• The essential benefit of Cuno filter housing compared to plate and frame filter presses include the elimination of;
• External contamination,
• Leakages in the edges
• Loss of integral products
• Extended tiresome change-out frequencies.
• It offers ideal sealing compression to inhibit filter bypass even under the most difficult process circumstances.
• The housing guarantees proper and effective installation of the cartridge, thus enhancing system integrity.
• It is suitable for a variety of batch sizes.

From small through to large consignment sizes.

It also sustains different rates of aqueous flows ranging from 2gpm to 75 gpmor 500 to 17000 lph for every housing.

• Minimizes the chances of adhesion of bacterial or particles
• It delivers a solution to the system from a single source.
• It does not consume floor space.

The housing only requires minimum floor space.

It is easy to dismantle, thus enhancing easy tiding.

• Due to the stainless steel material, the housing is corrosive resistant, resistant to varying temperatures, durable, has a mirror-like surface finish, and easy to construct.

The Cuno filter housing meets the required sanitary quality standards that are mandatory in:

• Pharmaceutical industries
• Food and beverage industries
• Microelectronics industries
• Fine chemical industries

In these industries, the Cuno filter housing aids in the filtration and separations of components.

Some of the particular applications of the filter housings are included in the following:

• Instrumentation filters.
• Sample systems and analyzer filters.
• Compressed Natural gas (CNG) filters for dispensers.
• Compressed air filters
• Pressure regulator filters
• Portable gas analyzer filters
• Automative gas analyzer filters
• Diesel analyzer filters
• Wellhead control panel filters etc.

Now stainless steel forms the basis of material construction of the filter housings because:

• The material is resistant to heat up to certain upper limits.
• Highly resistant to corrosion from severe chemicals such as sulphuric acid, iodides, and chlorides, etc.
• It is durable and easy to fabricate, weld, clean, and improve the grit finish to more smooth.
• Sustains varying changes in temperature, i.e., high to low-temperature variation.
• It is shiny and bright, thus enhancing its aesthetic appearance.

Stainless steel Cuno filter housing

We already know that stainless steel is the ultimate choice of constructing the filter housings.

Besides, the construction of Cuno filter housing utilizes either the 304 stainless steel or 316 stainless steel.

However, though the two types of material are suitable for housing, you should note that they all have distinct chemical compositions and features.

Compositions of SS304 v. SS 316.

The structures of the two grades of stainless steel incorporate both chromium and nickel.

Nevertheless, SS 304 has a chemical composition of 18 % chromium and 8 % nickel.

Whereas, SS 316 consists of nickel 10%, Molybdenum 2%, and chromium 16%.

Notably, the additional molybdenum component makes the SS 316 highly resistant to aggressive chemicals such as phosphoric acid, sulphuric acid, acetic acid, etc.

Functionality and practicability of the SS 304 v. SS 316

Stainless steel filter housing

· SS 304

Even though SS 304 chemical composition exempts Molybdenum, it is still resistant to oxidation and corrosion to some extent.

Thus the SS 304 material still works optimally in oxygen concentrations and at extreme temperatures.

Besides, you can swiftly fabricate them to have an attractive surface finishing.

The various applications of SS 304 include the manufacturing of tanks, pressure valves and vessels, tubing, filter housing, and piping.

· SS 316

SS 316 has excellent corrosion resistance to several harsh chemicals aside from being heat resistant.

This feature is due to the extra molybdenum component in its structure.

And that is what gives the SS 316 mileage over the SS 304 material.

Therefore, the SS 316 material forms the number one priority material in the pharmaceutical industry since it minimizes potential metallic stain.

Besides, even at high temperatures of aggressive liquids, the material still maintains its considerable resistance.

Again, the material is durable, easy to fabricate, clean, improve the grit finishing, and also weld.

The stainless steel materials are economically efficient construction materials in the filter housings.

You will not have to worry anymore about the frequent “eating up” of your filter housing and constant replacements.

All these may economically impact your business due to downtime and extra unplanned expenses.

Remember, the filter housing encloses the interior segments of the filter systems.

Generally, the working principle of housing is quite straightforward.

The component to be filtered enters the filter housing via the inlet.

It then uniformly distributes around the cartridge.

After filtration, the clean fluid exits through the outlet.

Aside from getting trapped into the cartridge, the contaminants may also adhere to the interior of the filter housing.

Cuno filter housings come in a wide range of shapes and designs dependent on the form of application.

Below is a brief description of the available types:

· Bag Filter Housing

Bag filter housing, also commonly known as bag filter vessel, come in two major forms, i.e., single bag filter housing or multi-bag filter housing.

Bag filter housing corresponds to the bag filter systems, which in turn large capacity of holding dirt.

During the changeover of parts, the filter housings easily and quickly open and closes.

The housing has an excellently positioned drainage compartment on both the inlet and bottom outlet side.

To maintain non-contaminated free-flowing fluid, you can use a multi-bag filter housing.

The multi-bag filter housing encloses several bag filters, thereby providing economically bulky filtration.

Such kind of housing has got design pressures of maximum 150psig, featured vent, and connected pressure gauges.

Some of the desirable features of the bag filter housing include:

• Accommodation of high flow rates of fluids while withstanding a pressure of a maximum of 1.5 Mega pascals.
• The sealing type is of positive o-ring, which enhances secure and easy operation.
• It Facilitates quick filter element changeover.
• Has heightened housing capacity, which reduces the fluid energy losses.
• Polished mirror grit surface to restrict adherence of dirt on the surface.

· Industrial Filter Housing

The industrial filter housing is available in selected varieties.

However, the major types include sanitary filter housing, lenticular filter housing, and sock filter housing.

i. Sanitary filter housing; this type is mostly applicable in applications which demand high precision of purity such as pharmaceutical, food, and beverage industries.

Moreover, they come in potentially five distinct connections such as SMS male, welded, DIN, tri-clover, and macon.

The design is cGMP compliant and features several control auxiliaries including manometers, sterile port, sight glass, etc.

ii. Lenticular Filter housing; this is an upright positioned housing design.

The vertical posture is essential in avoiding surface adherence of contaminants, consuming little space in comparison to typical plate filters.

Above all, the housing can serve you long since its means of washing is simply by backflushing and re-using.

Pressure gauges, vent valve, drain valves, etc. are some of the auxiliary components of this type of housing.

iii. Sock Filter Housing; though they are of several designs, they all look like the bag filter housing designs.

A typical example includes the ones attached to the filter bags.

The design thus enables the bag filter to operate with different levels of rates of fluid flow.

· Cartridge Filter Housing

This time is compatible with the proficient filtration of gases and liquids.

It also does sterilization and clarification.

In such filter systems, the cartridge extracts the contaminants and eliminates them through the outlet valve.

They also come in several varieties of pressure rating, dirt accommodation capacity, and rates of flow.

The cartridge filter housing has got properly fitted T-port/ in-line, open/L-port.

Apart from the standard fittings, the multi-cartridge filter housings must have threaded or flange connections.

· Duplex Filter Housing

The duplex filter housing assures constant, steady, and robust filtration operations not withstanding the piping techniques in place.

The design features dual stainless steel filter housings fitted with a three-mode changeover valve in between the housings.

Such design offers a high level of flexibility since you can easily shift your operations between the housings even if one breaks down or needs sanitation.

The notable features of the duplex filter housing include: interconnected duplex filters, easily available covers, compact housing, and spring fitted covers.

· In-line Filter Housing

In-line filter housings are suitable for use in oil and gas application system filters.

Most importantly, they are often used as process filters to protect other vital components from contamination.

These parts may include pumps, hydraulic circuits, and pressure reducers.

Consequently, you should fix the entire in-line filter system up the system pump to protect the fragile parts of the pump.

A few of the interesting features of the in-line filter housings include support core, bypass valve, electrical indicator, venting and draining connections, bolted cover plates.

Filter housing and element

Probably the most basic issue you must take into consideration is the filter element for your application.

Specify whatever you will be filtering, would it be liquid, powder, or solid components.

With that, you can now consider the following issues to be the most efficient Cunofilter housing for your application.

i. Nature of the filter medium; the medium you will be filtering has some distinct chemical properties that you have to evaluate.

For example, if it is corrosive, then select SS316LCuno filter housing, similarly if it requires a high sanitary level.

ii. Size of the particulate; establish whether you will be dealing in bigger sizes or smaller sized particles.

This information is key in picking the best filtration system with a corresponding Cuno filter housing.

iii. Material component; establish between SS 304 or SS 316 L that suits your application.

iv. Operational temperature and pressure; evaluate the operational conditions of your working and choose a Cuno Filter housing that matches such working conditions.

The recommended temperature and pressure are always indicated in the filter housing.

v. Inlet and outlet connections; select the type of inlet and outlet configurations that matches your pre-installed filter systems.

vi. Consider other general technical specifications of the device and pick the one built to the best engineering standards.

Always make it a trend to seek the technical manual of the Cuno filter housing.

This document will help you establish the specific parts and configurations of your filter housing.

Nevertheless, the following are some of the key parts you will find in all Cuno Filter housing.

Yet, still, you can customize the housing to incorporate auxiliary gadgets.

• Head and shell- it covers the inner components of the filter system, such as cartridges and piping.
• Vent and drain plugs
• Bolts –for de-assembling and assembling the housing.
• O-ring
• Seat plates
• Pressure gauge to consistently display the operational pressure.
• Connections such as flanges and gaskets

Different sizes of Cuno filter housing

The answer to this question is relative since it depends on the type of Cuno Filter housing you are using.

Some have an automatic backflushing system or self-cleaning such as the lenticular filter housing.

In contrast, other equipment is the manual type, which requires a physical control of the cabinet to kick startwashing.

Generally, you should, at all times, maintain a tidy working filter housing.

Cleaning depends on the mode of operation of the filter housing.

For an automatic filter system, you can apply a backwashing or self-cleaning technique.

Yet still, you can open the housing and manually scrap the contaminants off.

Please note that you should replace the filter housing when all operations are off.

You will need some simple tools for loosening and tightening bolts and screw nuts.

Depending on the working environment and size of filter housing, you may require a forklift or hoist.

First, open the vent valve in the Cuno Filter housing to reduce withstanding pressure to zero.

Next, you should now open the filter drain to allow the trapped fluid drain out.

With that, you may use your handle to lift off the housing cautiously, or you can just carefully pluck it off.

Finally, you can now fix the new housing.

First, you maintain housing by always cleaning it.

Secondly, replace the Cuno Filter housing when the need arises.

Always ensure you use the same specifications as the previous one.

Thirdly, often inspect the joints and bolts to ascertain their sealing quality.

If need be, you can replace them.

Note that the sealing parts must always be airtight.
