The VLG 98 uses compressed air to generate vacuum utilizing the Venturi effect. The heart of the system is a highly efficient Venturi vacuum generator that uses the energy in compressed air to create a vacuum and a secondary flow of air. Moderate vacuum flow is achieved with compact and cool operating equipment.

The operation of the VLG 98 is regulated. Once the preset vacuum is achieved, an internal vacuum switch shuts off the airflow from the compressor. The vacuum is constantly maintained at this level by an automatic valve that opens and closes the airflow from the air compressor as needed. The efficient design allows the VLG 98 to be powered by a relatively small air compressor. Two models are available allowing you to match the desired vacuum flow to the air compressor capacity.

The large gauges and the adjustment for the vacuum, air pressure and selector switch are conveniently located on the front panel. A vacuum filter is placed on the back of the unit for easy cleaning. The vacuum hose from the press is quick connected to the filter. The VLG 98 is easy to operate and requires very little maintenance due to no moving parts. It has a selector switch on the front panel allowing you to use it in either a regulated mode for vacuum pressing or in a continuous mode for vacuum clamping. Due to the moderate vacuum flow it is recommended for use only with small to mid sized systems. See warranty on contact page.

The generators may be used for either pressing or clamping operations.

Manual Venturi

The manual vacuum generator is a low cost, yet effective vacuum source. It uses compressed air to generate vacuum, utilizing the Venturi effect. They were designed to provide an alternative low cost solution for those who do not have the budget for a fully regulated system. The unit provides the advantage of a portable system for use in various countries with different electrical supply.

The VG 2 and VG 4 are manually controlled. They incorporate a manual valve which controls the air flow from the compressor and a check valve that prevents back-flow of air into the press once the air is turned off. A cleanable in-line air filter protects the unit and a silencer muffles exhaust noise to 68 db.

When vacuum is achieved the operator may close the air valve. This eliminates excessive use of shop air and frequent cycling of the shop's air compressor. To maintain the vacuum level inside the press the operator occasionally opens the air valve or leaves the air valve slightly open to let air bleed continuously through the venturi. See warranty on contact page.
