The ventilation unit Filters ISO ePM1 are custom-made and equipped with extruded technopolymer frame.

These filters can be configured with a choice of front dimensions and 25 or 48 mm thickness and contain a pleated polypropylene filter element manufactured in a clean room using the latest technology.

Ventilation unit filters in ISO andPM1 with plastic frames can be made in all sizes and are compatible with ventilation systems with 25 or 48 mm thick housing.

The AEROFEEL ventilation unit filters are made with special polypropylene filter elements composed of a coarse fiber spunbond backing layer to which a layer of fine meltblown fibers is added, giving high efficiency even for pollutants of tenths of micron particle size.

The filter material is pleated with high-precision machines, and the pleats are kept at calibrated distances with solvent-free EVA adhesive separators.

Features of ventilation unit ePM 1 minipleat Aerofeel filter

  • The regular pleats serve to increase the filtering surface even with small frontal dimensions;
  • the large filter surface allows for high accumulation, higher efficiency, and low resistance to air passage;
  • the tailored frame makes the ventilation unit filter compatible with popular controlled mechanical ventilation systems;
  • the AEROFEEL ventilation unit filter is made of heat-resistant technical materials without metal parts, moisture-resistant, self-extinguishing and solvent-free.

Main uses of the customized Minipleat filter

  • Domestic and industrial heat recovery systems;
  • fine filtration in air handling units;
  • prefiltration of absolute filters in pharmaceutical environment;

What heat recovery ventilation systems are used for


Heat recovery systems, often known as controlled mechanical ventilation or HRU abbreviated as ventilation unit, work by exchanging heat between the incoming outdoor air flow and the outgoing air flow.
In winter, the heat expelled with the indoor air is transferred to the incoming flow; in summer, the fresh outgoing air cools the incoming flow.

The heat exchanger divides the incoming and outgoing flows into small ducts that remain separated by large-surface area diathermic walls and promote internal energy exchange of the flows without them coming into contact.

If airborne solid particulates were to settle on the exchanger walls, the exchange process would be less efficient and the recovered energy would decrease.

Where ventilation unit filters are placed


The inlet filter, ISO class ePM1 (F7), is placed upstream of the heat exchanger and has the dual purpose of ensuring clean indoor air and protecting the heat exchanger from external solid pollutants.

The exhaust air filter, often ISO Class Coarse (G4) or ISO Class ePM10 (M5) is placed between the indoor rooms and the exchanger, and serves only to prevent the accumulation of household dust on the exchanger walls.

Construction and certifications of the filter for ventilation unit


This Aerofeel ventilation unit air filter employs an advanced PP synthetic fiber filtration paper laminated to spunbond – meltblown layers, without glass fibers, as filter material.

These filters are in efficiency class according to Standard EN779:2012, ePM1 60% according to ISO 16890. Fire reaction class F1 according to DIN 53438. The dense folds are evenly separated and calibrated with the highest quality EVA hot melt.
