Dry blade vacuum pumps (oil-free) can run continuously, but only if it is a clean dry environment. Dry vacuum pump pumps can run with any kind of pressure, which many other forms cannot. There are no wear parts other than the slats and filters of this type, so maintenance only consists of replacing slats and cleaning the filters.

The most important uses are: suction cups conveyor belts, automatic machines, woodworking machines. Dry-running lamella compressors have no special restrictions on use, except for the maximum working pressure which must not exceed nominal value.

The side channel blower construction is based on the principle of horizontal ducts.

A specially designed fan impeller forces the inlet air flow to follow a spiral channel; the air flow is thereby subjected to repeated accelerations resulting in the achievement of a high differential pressure or vacuum due to the use of the side channel fan.

The impeller is mounted directly on the motor shaft and the rotating parts are dynamically balanced to ensure almost vibration-free operation.

Both fan housings and wheels are made of cast aluminum for maximum robustness and easy handling.

The side channel blower does not require lubrication because there are no contact points between static and rotating parts.

The special features of our fan impeller design make it possible to avoid any accumulation of foreign matter, oil or dust inside the fan. If the side duct fan is used for an aggressive medium with high residual content, it makes it easy to build it quickly and easily for dismantling the impeller. inspection.

A volumetric roots lobe pump mainly consists of a stator housing, incl. two symmetrical pistons with three toothed gears rotating in opposite directions at the same speed.

A unidirectional screw threaded gear always ensures correct spacing between pistons and adhesion to precise common tolerances that are so important to maintain good mechanical operation and high volumetric performance. The transported gas enters the chamber which arises between the stator and the pistons. The resulting pressure depends on the friction slip in the gas pipes and the system pressure (system pressure).

The volumetric performance of the capacity fans is constant, enabling operation under changing pressure conditions. The recorded amount in six separate sections is aspirated and compressed for each full rotation of the drive shaft. A constant pressure and an increased fan speed increase the exhaust gas flow proportionally. The recorded power automatically adjusts to the current operating time, which prevents unnecessary power consumption.

The missing friction between the pistons makes lubrication in the compression chambers superfluous, which means that the air intake is completely oil-resistant.

This is one of the greatest benefits of these volumetric roots lobe pump and is an extremely important feature of chemical processes and applications that require a very low level of contamination.
