AirCraft Gravity Feed Spray Gun Paint Cup Ventilator Head (SG AS1001P-28)
At a Glance: Ventilator cap that prevents vacuum lock and keeps paint flowing
The AirCraft SG AS1001P-28 Ventilator Head is the small but essential cap component used on a gravity feed spray gun paint container. Its job is simple: let the cup breathe. As paint leaves the container, air must enter to prevent a vacuum forming, otherwise your spray pattern can sputter, starve, or become inconsistent. Replacing a cracked, blocked, or missing ventilator head helps restore smooth paint flow and steady atomisation for cleaner, more predictable results.
A gravity feed cup relies on controlled venting to maintain pressure balance. The SG AS1001P-28 ventilator head helps avoid “glugging”, surging, and spray interruptions by allowing air into the paint cup as the coating is drawn into the gun.
