The “Canneed ALT-600 / ALT-800 Leak Tester for Aerosol can” is used for testing the leakage of Aerosol cans. ALT-600 can test 6 cans at the same time, and ALT-800 can test 8. The permeability tester for aerosol cans blows up the cans up to a maximum of 10 bar and submerges them under water. At the leaking spots of the can then visible air-bubbles escape.
A special clamping system enables to measure different diameters and heights with one device. Two pressure levels can be set with the tester. The first is meant to hold and seal the can, the second step sets in when the mount with the cans has reached the lowest position. The maximum test pressure is 10 bar.
The air bubbles that cling at the can may be removed with a brush through the slots within the cover plate. If new air bubbles appear at the same spot, this is a sign of leakage.
The operator determines the period of time the cans are under water. If he switches the by-pass lever and presses the two button valves, the cans deaerate and are lifted out of the water.
The whole test cycle is automated and is pneumatically controlled by pressure regulator valves. Silencer ensured that the noise is reduced.
Advantages:
Cans are freely suspended in the water, no extra clamping force
Clamping independent from can diameter
Simple operation
End and side seams visible
Simple clamping device, takes only seconds to clamp or take off the cans
Pneumatic controlled by the handle to make the cans dip in or lift out of the water
