Filter Development

Research and Production Company MICROSISTEMA LLC deals in the development, production and sales of air filters of its own brand PHAUF.

PHAUF air filters for industrial and household ventilation and air-conditioning systems meet the strict requirements of the European standard EN 779: 2012 “Particulate air filters for general ventilation - Determination of the filtration performance”.

PHAUF products presented in the international exhibition “The World of Climate – 2020” in the Central Exhibition Centre Expocentre (March, 2020) received the highest estimates of the guests and participants.

What filters we produce

Research and Production Company MICROSISTEMA LLC produces high-quality air filters of European level of the following types:

  • Panel
  • Cassette
  • Pocket
  • Compact W-shaped
  • Absolute EPA/HEPA/ULPA

PHAUF filters for ventilation systems are:

  • Presented in different modifications
  • Developed in typical sizes and according to the individual requirements of the customer by PHAUF technical specialists
  • In compliance wuth the updated international standards

Highly effective filters EPA/HEPA/ULPA

Our company takes pride in its own production of highly effective filters EPA/HEPA/ULPA (purity classes Е10-Е12, Н13-Н14, U15-U17).

PHAUF НЕРА filters are developed with account of the latest world trends and produced as a part of import substitution program.

PHAUF absolute filters feature the effectiveness of 99.999995% in capturing the smallest infectious and aerosol particles over 0.05 μm, including COVID-19 virus, whose size is about 0.12 μm.

Individual assembly and vacuum packaging of the products is performed in clean premises compliant with ISO-7 class.

Each НЕРА/ULPA product is subject to quality control on with an automatic TOPAS scanner.

We produce highly effective PHAUF filters routinely and against customized orders.

  • Filtering material: corrugated ultrafine fibre paper of the highest quality with the purity classes from E10 to U16
  • Filter package dimensions: from 300х300 mm to 1220х1220 mm
  • Height of the corrugated fold: from 20 to 100 mm
  • Divider (separator): Adhesive based on polyolefin melt
  • With two-sided mesh (galvanized, with powder coating) or no mesh
  • Sealing: two-component polyurethane glue
  • Sealing: polyurethane, gel compound
  • Casing material: anodized (or non-anodized), extruded alumunium

Highly-effective PHAUF filters is an ideal solution for creating a controlled microclimate in the clean premises of medical institutions, pharmaceutical productions of GMP standard, microelectronics and foodstuffs industry.

W-shaped filters

We produce customized compact W-shaped air filters of purity classes from M5 to F9:

  • As pre-filters to absolute НЕРА/ULPA filters
  • For fine air cleaning in the ventilation and air-conditioning systems
  • For gas turbine and compressor units

Advantages of compact W-shaped PHAUF filters:

  • Increased DHC
  • Extended term of operation
  • Filter package from fine pleated glass fibre is protected with reinforced net
  • Lightened impact-proof thermal resistant filter case is made of high-quality polystyrene
  • Sealing of the filter package within the case perimeter is made with two-component polyurethane glue
  • Foamed polyurethane sealing is applied by seamless adhesive method

Pocket filters

We produce pocket-type air filters of different modifications (at the request of the customer) for any systems of combined input-exhaust ventilation equipment:

  • Rough cleaning (G3-G4 classes)
  • Medium cleaning (M5-M6 classes)
  • Effective fine cleaning (classes F7- F9)

The filtering pockets are made of high-quality volume materials of the relevant filtration classes:

  • 100% polyester
  • Мeltblown
  • Combined SMS

The dimensions of the filters, depth and quantity of the pockets vary depending on the customer’s requests.

Panel filters

We suggest using panel design air filters:

  • For basic air cleaning in the ventilation, air-conditioning and air heating buildings
  • For cleaning the working air of dusty / contaminated production premises, coating cameras, chemical laboratories

Filtration classes of PHAUF panel filters: from G2 to G4

Case frame:

  • U-shaped allows filter regeneration
  • Produced from galvanized steel, stainless steel, plastic.
  • Profile width – 25, 48, 96, 100 mm
  • Dimensions of the frame: standard, customized upon request

Dust-holding filtering materials of the relevant purity classes are used:

  • Synthetic volume fibre made of 100% polyester
  • Fibre paper

Cassette filters

You can order cassette filters for preliminary (rough) air cleaning for industrial and household ventilation units of various filtration classes: from G2 to M5

Case frame:

  • U-shaped case frame allows for filter regeneration
  • Made of galvanized steel, stainless steel
  • Made of high-impact plastic
  • Profile width (at the request of the customer) - 20, 25, 30, 35, 40, 48, 96, 100 mm
  • Frame dimensions: standard or customized at the request of the customer

Fixation of the corrugated filtering material:

  • on a supporting mesh
  • without a supporting mesh (thermostated)

Filtering materials:

  • Chemical textured fibre
  • Materials of coal cinder

Innovative filtering materials

Alongside the traditional brands of textured fabrics made of polyether (polyester) fibre and glass fibre, innovative filtering materials are used for the production PHAUF filters.

Paper made of ultrafine fibre paper

The filter packages of absolute HEPA filters are produced from highly effective filtering materials formed by ultrafine twisted combined glass fibres with the thickness of 0.5 μm on average.

Corrugated filtering ultrafine fibre paper captures aerosol, biological and radiation particles of 0.3 μm with the effectiveness of over 99.95%.

Combined filtering material SMS

Three-layer synthetic filtering fabric SMS (Spanbond – electrostatically charged Meltblown – Spanbond) has higher dust holding capacity and the ability to capture the particles that are hard to remove (purity class from М6 to F9).

Pocket filters made of combined SMS are characterized by long service life and high air purity effectiveness.
