Technical Specification

The Carbon Panels:
207C 55 CFC active carbon granules chemically bonded to give a uniform panel, each panel is covered with white non woven cloth to protect the carbon surface.
Activated carbon filter units to reduce levels of atmospheric pollution gases emissions. 4 Panels approx. 140mm(H)x400mm(L)x30mm(Thick) arranged in a V formation will give a rated volume of approx 150lts @ 22Pa clean pressure drop, giving extended filter life and prolonged dwell time of 0.27seconds total through 4 panels giving very high adsorption at lower flow rates.

The G4 Pleated HEPA Pre Filter (BSEN 779-2012):
Rated volume 80 lts with clean pressure drop of 40 pascals. Non woven fibres manufactured to give high holding capacity 90% arrestance at average
particle size 0.4UM. Frame made from Aqua Kote cardboard and glued with J2013 adhesive.
BSEN779-2012 class G4 final resistance 200 pascals

Filter Case: Tested By BISRIA test no59719/1 ( tested for leakage and flow performance criteria)Built entirely from pre galvanised steel, fully sealed for optimum performance in accordance with BS EN 15727:2010
Class C achieved with additional sealing to unit, full test results available on request
powder coating as an option in any standard RAL/BS colour.
Bottom entry for access to filters and easy HEPA pre filter removal.

Air Flow:
The unit incorporates a unique air displacement system which ensures uniform flow through the unit.

Case Performance:
The case was tested to laboratory standards for leakage. positive pressure to 450 Pa and negative to -750 Pa.
