2020-01-09e-MOCarz

The e-MOCarz electrostatic precipitator is a new product from the MOCarz series of anti-smog filters dedicated to domestic mechanical ventilation systems. The e-MOCarz filter ensures the highest filtration efficiency, as high as 95%, of ePM1 and ePM2.5 particles, i.e. the main component of smog. It effectively purifies polluted air extracted from the outside, without significantly affecting the operation of the entire system (power consumption constitutes only 9W, and the filter itself is reusable). The electrostatic precipitator due to its unique design is a more efficient solution than standard non-woven filters (e.g. HEPA filters), which clog up much faster, thus reducing the efficiency of the entire ventilation system. In addition, depending on the level of contamination, HEPA filters should be replaced at least every 3 months, if not more often, while the e-MOCarz filter is washable.

How does an electrostatic precipitator work?

Polluted air initially passes through a steel mesh pre-filter (which retains larger fractions), then is positively ionized in an electric field due to the “crown discharge” effect. In the last stage, the previously charged particles, are pulled by electrostatic force toward horizontally mounted aluminium plates (electrodes) and build up on their surface.

BENEFITS:

• The high filtration efficiency – 95% of ePM1 and ePM2.5 particles
• The compact design makes it an ideal filtration solution for residential mechanical ventilation systems with a capacity of up to 720 m³/h
• Aesthetic design , powder painted  galvanized steel
• Additional filter modules available on request - ionizing module (purifying and revitalizing the air) and active carbon module (higher air purification including odour reduction)
• Higher performance and service life compared to traditional HEPA nonwoven filters
• Low airflow resistance, ergo low energy consumption by air handling equipment, e.g. RAHUs
• The perfect complement to the mechanical ventilation system with heat recovery
• Renewable filter – simply rinse the filter with water
• Wall-mounted or from the ceiling (mounting strips included)
