In the photographs: The lab’s safety hoods/cabinets - Barometric shutters assembled at the top of the safety hood/cabinet, an air inflow and filtering chamber, assembled on the roof of the building.
The safety hoods’/cabinets’ interior - polypropylene.
The work area - Terspa Top Lab Plus with a thickness of 20 mm.
Air entry - an actively ventilated stainless steel 304 lower cabinet.
Air removal - through PPS, PVC ducts up to the UV protected PVC blower together with a motor outside the removal zone. To “compensate” for the air extracted from the room, an air entry system was created combining barometric shutters made of stainless steel 304 which operate according to the fresh air needs. A chamber was assembled on the roof to receive and filter fresh air. The fresh air undergoes filtration only (not air-conditioned) and is directed from the roof to outside the safety hood/cabinet toward the work chamber and extracted accurately according to the standards through the barometric shutter that offers a significant energy saving.
