‘Oil free’ single cylinder and bi-cylindrical piston air compressors, also available in silent version with cooler and dryer.
The dry-type (oil-free) OFP series is designed mainly for medical and dental use. This is possible since the compressor group is not lubricated and, on top of that, the generated compressed air is cooled and subsequently dried, in order to eliminate all condensate residue that is produced during the compression process; the air vessel inside surface is treated to avoid any possible contamination
Thanks to the oil free pump the compressor produce high-quality compressed air, without presence of oil residual. With the cooler and dryer version, the air becomes perfectly dry, and therefore eliminates problems with eventual condense.

The compressors are designed as fully integrated, compact silenced packages with drive motor, coolers, moisture drains, reverse osmosis system and filtration along with a controller to ensure optimum efficiency and reliability. The Full Feature versions include the integration of environmentally friendly refrigerant dryers to ensure compliance with your air quality requirements and make the best use of your valuable floor space.
The Integrated frequency converter of the AQ VSD series varies the speed of the drive motor in order to exactly match the changes in your compressed air demand, thus using the minimum amount of energy and more than justifying the additional investment.

VANTAGE
DC fuel transfer pumps
The all new DC pump for plant equipment featuring new innovations in design and compact in size, incorporating a new level of pump intelligence allowing the pump to monitor its own activity and performance.
Studies have shown that, in the majority of cases, fuel-transfer pumps break down because of improper handling by users, including excessive or extreme use, accidental start-ups, or simple carelessness, that can leave the pump running for hours on end. Breakdowns translate into loss of time and money while waiting for the pump to be repaired. These difficulties are overcome with VANTAGE. Thanks to new, internationally patented technology, VANTAGE automatically prevents situations from becoming critical.

Inside the rotor slots (1), positioned eccentrically in the pump cylindrical housing (2), free moving vanes (4) are inserted (3). When the rotor turns, the centrifugal force throws the vanes against the cylindrical wall creating multiple chambers. The air taken from the inlet port (4) is compressed inside these chambers and is thrown out to the outlet port (5).
