CFI Pocket Bag Filter

Application

CFI Pocket Bag Filters are designed for air conditioning and general ventilation application. Typical users are hospitals, pharmaceutical plants, power stations and industries which require very high efficiency of filteration.

Construction

CFI Pocket Bag Filters are constructed from three distinctive filter media each fulfilling a specific duty. The first stage is a glass fibre which acts as a pre-filter and at the same time gives a large dust holding capacity for a longer life. The second stage is a super fine filter media which captures dust particles as low as 1 microns and finally there is a cerex backing which prevents fibre migration. The bags are finally fitted in metallic.

CFI High Efficiency Particulate Air Filter (HEPA)

Application

The acronym HEPA stands for High Efficiency Particulate Arrestance
(you may see others using variants for the letter “A” like arresting, arrestor, or even simply air, but they all convert the same basic meaning ‘to capture’)

A ‘true’ HEPA is also known as an ABSOLUTE filter because of its efficiency.

 

 

For a filter to be called a True Hepa it must retain and filter out all particles from the air that passes through it down to 0.3 microns in size at an efficiency rating of 99.97%.

The efficiency of a true Hepa does not decrease during its life; it actually increases.

For a filter to be labeled ‘True Hepa’, it must be certified 99.97% efficient in capturing 0.3 microns respirable-size-particles (RSP)
according to the U,S. Millitary standard MIL-STD-282  commonly known as the D.O.P.test.

True Hepa filteration is recognized as one of the must efficient air filteration methods known and proven to remove airborne particles down
to 0.3 microns and are used for the purpose of  absolute filtration in nuclear installations, toxin research laboratories, pharmaceutical industry, clean room system, laminar flow working bench, hospital sterile area, space application, man made fibre Industry, food processing zone, biological centres and many other areas.

Construction

Absolute HEPA filters are made out of 100% water and fire-resistant imported micro glass fibre paper. The paper is pleated and the pleats are separated by super fine corrugated aluminium foil and finally fitted in an aluminium frame. Epoxy-based adhesive is used all over from the inside for effective sealing of gaps, and also neo-prene-sponge rubber gasket is provided on the flanges to effectively seal the construction from the outside.

Size

Usually in 150 mm to 300 mm depths, it is also available in wide range of size, capacities and efficiency ratings as per the system requirement.

TECHNICAL DATA

Recomended Air Velocity :0.45 m/sec. to 1.2 m/sec.
Initial Pressure Drop : 20 – 25 mm Wg.
Final Pressure Drop : 75 – 100 mm Wg.

We manufacture and export a range of air washer. The typical applications are in textile mills, jute mills, air cooling and ventilation requirements. They are available in modular designs (panel type) and standard units.

 

 

CYCLONE SEPERATORS

Fiber and dust will exist, and our separators may be used in place of or in front of filters. This allows for larger particles to be broken down before the air is filtered. Also, cyclone separator systems are used to separate two immiscible fluids with different densities within a confined amount of space.

 

CFI ACTIVATED CARBON FILTERS

EFFICIENCY COMBINES WITH FLEXIBILITY

APPLICATION

By means of the aimed utilization of certain characteristics of activated carbon we have been in a position to reach the highest status in the clean-keeping of air from gaseous noxious matter through the application of equipments, developed by ourselves CFI Activated Carbon filter are used for eliminating noxious matters from the Air.

CONSTRUCTION

CFI Activated Carbon filters are made of fine Non woven polyester media impregnated with powder coated treated with PU base materials and finally fitted in Metallic frame.
Size of the filter is generally in the range of 610 x 610 x 100 mm to 610 x 610 x 300 mm Cassette Type ( Box Type )

TECHNICAL DATA

Recommended Average Air velocity : 0.5 m/sec to 2.0 m/sec.
Velocity through Media : 0.18 m/sec.
Pressure drop : 15-20 mm w.g. ( Initial)
Average absorption : 85% to 90%

In practise this means :

• Lower quantity of activated carbon for the same performance
