The Hall PCAT Air Flow Tester is a pre-conditioned air flow tester
designed to be utilized as a maintenance analyzing tool by GSE / HVAC technicians. It enables users to determine the actual temperature and air flow being supplied into the aircraft that is being serviced by the external pre-conditioned unit.
It is used to determine:
Actual temperature and air flow being supplied into the aircraft that is being serviced by the external pre-conditioned unit
PCAT Air Flow Tester connects to the aircrafts external conditioned air opening
Supply hose connects to the flow instrument panel by means of the 8” aircraft hose adapter
Flow instrument panel connects to the flow tester tube at its identified location points.
There are no adjustments that need to be (or can be) made to this flow instrument panel. The test gauges are all calibrated from the manufacturer’s facility.
Temperature gauge displays the actual air temperature being supplied into the aircraft
Air speed gauge provides the actual air flow being supplied into the aircraft
Inches of water column is the actual back pressure being supplied by the aircraft
Conditioned air flow requirements – steady state airflow charts
are listed in the manufacturers aircraft manual
PCAT Air Flow Tester has a general summary chart of these
requirements in the operations manual and a placard on the flow meter instrument box
Always follow the aircraft and airline maintenance requirements for the required readings
No tools are required to utilize the PCAT Air Flow Tester
Connect the Air Flow Tester tube to the aircraft's external conditioned air opening
PC Air units discharge hose connections to the PCAT Air Flow Tester tube by means of connecting the 8” aircraft hose adapter. PCAT Air Flow Tester instrument box connects to the air flow tube
PC Air unit is started and the air flow being supplied to the aircraft are able to be analyzed
The PC Air Flow Tester and tube must be removed from the aircraft before flight
