We produce a vast range of minipleated filters for efficient cleaning F6-F9 classes High Efficiency Particulate Air HEPA filters of H10-H14 classes and Ultra Low Panetration Air ULPA filters of U15-U16 classes. 2 versions of filters are produced according to their structure:

-with aluminum separators (Fig.1), where the adjacent pleats of the filter medium are interlaid with separators of aluminum foil;
-with minipleated filter packets (Fig.2), where the adjacent pleats of the filter medium are interlaid with special thin plastic threads.

Panel minipleat filters of type PMF-F (F6÷F7 classes)

Minipleat panel filters of type PMF-F are used for cleaning of supply and exhaust air in systems of ventilation and air-conditioning. Filters are capable to provide effective air cleaning and are made of F6÷ F7 classes. Compactness of these filters allows to solve problems of the effective air cleaning in case of limited place of their accommodation.

Particulate air filters CPF (F6÷F9 classes)

Particulate air filters CPF are used for cleaning of supply and recirculation air in systems of general ventilation and air-conditioning in rooms of various purposes. These filters are generally used for II step of air cleaning (fine cleaning in accordance with EN 779) after less effective filters. Filters CPF can be used for replacement of pocket filters of type PF since they are sufficiently compact.

Particulate compact miniplect air filters filters PGPF (F6÷F9 classes)

Particulate air filters filters PGPF are used for effective cleaning of air from finely dispersed aerosols in systems of general ventilation and air-conditioning. They can be also used as pre-filters before highly effective and ultra highly effective filters HEF (HEPA and ULPA).

The filters can be used in various industries, including for air cleaning in gas-turbine and compressor units.

High flow minipleat filters of type HFMF-F (F6÷F9 classes)

High flow filters of HFMF-F type are used for effective air-cleaning (clearing class from F6 up to F9) from fine dispersing aerosols in systems of general ventilation and air conditioning. These filters can be used as a precleaning filters, installed before HEPA and ULPA filters of type HEF.

At cleaning of large volume air these filters can be placed in section of folded filters of type FCCF (to look the catalogue NPP Folter).

Filters of type HEF (filters НЕРА)

Filters of type HEF (filters НЕРА) are used for highly efficient (final) cleaning of air and sterilizing filtration in medical institutions, at pharmaceutical enterprises, and in cleanrooms of other industries (microelectronics, microbiology, food, etc).

Filters can be also used for cleaning of extract air form harmful microorganisms and radioactive aerosols at bacteriological labs, nuclear power plants, etc.

Compact high flow HEPA filters with minipleated packages of type HFMF-H 

Compact high flow filters with minipleated packages of type HFMF-H (filters HEPA) are used for highefficient (final) cleaning of air and sterilizing filtrations in medical institutions, at enterprises of pharmaceutical industry, as well as in clean premiseses of other branches of industry (microelectronics, microbiology, food and etc.). The particularity of these filters is their high air flow.

Filters are to be also used for cleaning of extract air from harmful microorganisms and radioactive aerosols at bacteriological labs, at nuclear plants etc.

For installation of HEPA filters in clean rooms we produce airdistributing modules of type ADM, and filtering chambers of folded filters of type FCCF - for high efficient cleaning of large volume air in which filters of type CPF, HFMF-F, CCF, HEF, HFMF-H can be installed. Filter of type CMPF can be placed in filtering chamber of pocket filters of type FCPF.

Airdistributing modules of type ADM

Airdistributing modules of type ADM (hereafter “the modules”) for air supplying and distribution in cleanrooms.

Modules are used in a structure of a clean room: on walls or a ceiling, where they are sealed then. Highly effective filters HEF (НЕРА) of class Н10 to Н14 are placed in the module.

Modules can be used in cleanrooms of medical establishments, in pharmaceutical, electronic, food, etc. enterprises.

The filtering chamber of folded filter of type FCCF

The filtering chamber of folded filter of type FCCF is used for installation and hermetic sealing of filters of type HEF (CPF, HFMF-F,  CCF, CMPF, HFMF-H) with dimensions 592x592x292(300) in systems of general ventilation and in air conditioning of household, administrative and industrial buildings. The filtering chamber is placed in the structure of a ventilating system and is its part.

Filters HEF are manufactured in classes F6 and above and in some cases require installation of filters of lower efficiency before them. In this case, the filtering chamber of pocket filters of type FCPF (see the catalogue of "NPP "Folter") with prefilters PF of required class and pocket length of up to 600 mm can be set up before the filtering chamber FCCF.

By request filtering chamber FCCF can be supplied with elements for installation and hermetic sealing of pocket filters PF with pocket depth of no more than 250 mm or compact miniplect filters CMPF.
