Clean Room Pass Thru Air Locks are for the transfer of parts and equipment in and out of a cleanroom. They reduce the need for people to enter the cleanroom. Contamination is eliminated
because of the reduced "traffic" within the cleanroom. Clean Air Products' Series 18 pass thru air locks feature polypropylene or stainless steel construction - not particle board.
The Series 18 clean room pass thru air locks are manufactured using two types of materials; white
polypropylene and stainless steel. The polypropylene units are constructed of 1/2-in. white sheets that are welded together. Polypropylene is a solid plastic that contains no
particle board and is a superior construction material. Pass thru cabinets made with
laminated formica over particle board construction can crack, chip, delaminate, and
promote the growth of biological contamination. The Series 18 pass thru air locks use solid polypropylene
sheets to prevent this type of deterioration.
The stainless steel cabinets are constructed with welded stainless steel shell. They are
extremely strong, durable, easily cleaned, and provide a superior look to your cleanroom. The stainless pass thru air locks are all metal except for the viewing window. They contain contain no particle board.
The air lock doors are made with a heavy-duty stainless steel frame, stainless steel continuous hinge,
tempered safety glass viewing window, closed-cell PVC door gasket, and 90 degree turn-knob
latch or cam action chrome-plated latch on larger units. The stainless steel door frame design adds strength, prevents long-term warpage, and prevents cracking of an all plastic door. (Cracking of all plastic doors is a common problem.)
Mechanical door interlocks are available to prevent both doors from being opened at
the same time. This prevents cleanroom depressurization and infiltration contamination.
