Smoke test & measure static pressure

The purpose of this test is to see whether there is a static pressure in the room prior to the door fan test. The door fan is not running and smoke is puffed in front of an open hole in the blower. If it moves slowly or not at all, no pressure exists. Minor pressures are cancelled out by testing both directions so we are therefore looking for significant movement of 2 mph (3kph). If the zone outside the enclosure is not completely connected with open doorways then you must check across each wall this is not connected. Walls to outdoors can be ignored.

If there IS smoke movement, the magnitude of the pressure must be measured with the room gauge or the handheld gauge.

Check to see if there is any static pressure by puffing smoke near a known hole at the door. If the smoke moves, the next step is to measure the magnitude since the smoke is the best guide to its direction.

If the smoke moves, a handheld gauge or room gauge with tube under doorway is used to measure the static pressure.

Analog handheld gauge must be held firmly against a vertical surface to ensure zero shift is kept to a minimum.
