ABOUT THIS EQUIPMENT

Built around the requirement.

An automatic roll filter converts the pressure difference across the media into a sensor signal and advances a fresh roll of filter media automatically, so the pre-filter stage keeps its airflow without manual media changes. The frame is metal - powder-coated steel, aluminium extrusion or stainless steel - and suits harsh environments. A photoelectric control tracks the media, with an LCD display of status, local audible and visual alarms and a remote alarm contact. Four versions are offered. The standard version covers general ventilation pre-filtration. The self-cleaning version adds a module that brushes the media roll to extend its life between changes. The explosion-proof version is built for areas with flammable media; the required Ex rating, for example Ex d IIB T4, is confirmed with the order. The duct-type version is built into rectangular or circular ductwork, runs under high negative pressure, and carries a large media roll for long service intervals and continuous year-round operation.
