Centralized automatic lubricating systems are designed to deliver the right amount of grease at the right time to prevent too much or too little lubrication. These systems pressurize grease, deliver it to the needed sites and then vent the system to relieve pressure. The proper grease is
essential for the system to function correctly. The grease needs to flow under the applied pressure at the temperature of the system and recover with venting so that it can be pressurized again. This test uses a Ventmeter to measure ventability of grease under conditions similar to
those used in industrial systems.

The ventmeter must be fixed on the wall for ease of operation. It is provided with sturdy stand for supporting the grease gun. The gun can be dismantled and the grease can be filled. Approximate 1KG grease is required. After filling the grease re-assemble the grease gun on the system.
