construction details :-
the reverse laf unit is fabricated in 18-gauge ss-304 pvc coated imported material complete with ss-304 side panel and pencil coving.
d p enterprise filters comprising the prefilters and intermediate filters made of depth media, specially treated with anti-fungal and bactericidal reagents to inhibit growth of micro-organisms, possess enhanced characteristics like fire retardance and water repellence. This permits washing of the filter with water. Efficiency rating : eu 5 grade equivalent to 40-60% on ashrae for prefilters and eu 7 grade equivalent to 60-90% on ashrae for intermediate pre-filters.
final filters ( eu-13)
minipleat type hepa filters made of micro fibre-glass media pleats, efficiency rating: 99. 97% down to 0. 3 microns when tested as per ies recommended practice.
two hepa filter blank, the main blank configured for continues clean down of work space and bleed hepa filters comprising the external blank configured for 10% displacement.
