Air extraction within the unit
Air extraction within the unit
Air extraction within the unit is required if:
•
the chemical composition of the test liquid used specifies it
•
there is no ventilation and/or air conditioning in the CTU operating room
•
an easily volatile test liquid is used.
Check the Safety Data Sheet of the test liquid.
During extraction, observe the required volumetric flow and check for proper
wiring in the entire space ventilation equipment.
Note when using the test liquid G 60 Spezial
The recommendation with air extractors when using the test liquid
G 60 Spezial is:
If an air exchange of 15 times the room volume of the operating room / hour
is guaranteed in operating rooms with a volume ≤ 75m³, no air extraction in
the machine room is required.
