Cooperation with Parker Haniffin Company

The former supplier of electrostatic filters, United Air Specialists (UAS), was purchased by Parker Haniffin Company in 2018.
Our company Work 4 is pleased to have been chosen as a business and service representation company for sale and service of electrostatic filters Smog Hog in the Czech and Slovak Republics in 2019. All common spare parts for our electrostatic filters are in stock in Slovakia, therefore, in comparison to the past, the delivery time of spare parts has been significantly reduced.

SMOG HOG® Electrostatic air filter

Comprehensive solution against oil mist, oil smoke, plasticizer vapours and emulsion nebula.

High separation performance especially of ultrafine particles smaller than <0.001mm is 96 - 99% secured by a simple, but even more efficient structure. Contaminated air is sucked in by a vibration damping fan to first reach a mechanical pre - filter which separates larger pollutant particles and ensures the even distribution of air flow.

The pre-treatment filter is followed by the so-called ionizer. In the ionizer, the remnants of the finest pollutant particles are charged positive by use of electrons and ionized molecules of air at the intervals of one second.

The air purification itself is performed in the collector. The collector consists of a series of vertical metal boards placed parallel to the stream of harmful substances. Inside the collector, the positively charged pollutants are diverted into the induction electric field in the direction of grounded boards.

The vertical position of the metal plates guarantees excellent drainage behaviour as the separated harmful substances can simply get out by the siphon. The collector plates where the sediment is caught can be cleaned and reused later.

We can do all of this for you in our modern cleaning facility.

Of course, harmful substances are disposed of environmentally.

Our filtration systems are also available in two-stage or multistage design. Filters free of the fan (XB) can be supplied for installation in ventilation systems as well.
