With decades of experience in diaphragm compressor technology, we have partnered with companies and government agencies worldwide to provide them with the optimum solution to satisfy their gas compression needs. A diaphragm compressor is a variant of the classic reciprocating compressor with backup and piston rings and rod seal. The compression of gas occurs by means of a flexible membrane , instead of an intake element. The back and forth moving membrane is driven by a rod and a crankshaft mechanism.

Nitrox systems use semi-permeable membranes to separate out a portion of the nitrogen in air. Nitrox mixtures, containing between and oxygen (O2), are then delivered to a high-pressure compressor to fill scuba cylinders or storage tanks, or to a low-pressure compressor for pumping to surface-supply divers.

Find all the manufacturers of membrane compressor and contact them directly on DirectIndustry. Nuvair nitrox generating systems use semi-permeable membranes to produce enriched air nitrox (EAN or nitrox). Our nitrox systems produce up to nitrox ( EANx40).

Used with a high-pressure compressor , the nitrox mixture is compressed for delivery to scuba cylinders or storage tanks for later use. Nitrox membrane systems are based around a special semi-permeable „filter“ called a membrane. The membrane is fed with very clean, low pressure air.

ETC instead of activated carbon filter: Reliable removal of carbons to protect the membrane. Oxygen content independent of ambient temperature: Constant cooling of the membrane to ensure optimum efficiency at all times.

This compressor system enriches breathing air with . With B-NITROX, BAUER is the only manufacturer in the world to offer a complete nitrox system certified by the TÜV. Air pumps for aquariums. The Nuvair Nitrox System uses a semi permeable Permia membrane to produce Orich air (Nitrox). The operation of the pump ensures sufficient oxygen supply of your fish. The water phase is further used as service liquid for the compressor , and hydrocarbons are fed to a collection tank for reuse.

A liquid-ring vacuum pump creates a vacuum of 2mbar to provide an additional driving force for the. In this range, membranes are the low-cost process, and most new small nitrogen plants use membrane systems. A simplified drawing of a nitrogen-from-air separation process and its performance is shown in Fig. The feed air is compressed to 8–atm with a lowcost screw compressor and then passed through a . The observation is attained due to the increased impact on the membrane permeance with more permeation at these conditions, which further amplifies the importance for incorporation of the JT expansion to accurately predict the membrane module separation performance. It uses a low pressure air source (or a high pressure air source regulated to low pressure) to force heated air through a special membrane system.

Compressor Power and Stage Cut The . There are two outlets from the membrane : one for the nitrogen vent, and one for the permeate ( enriched Oxygen mixture) that goes into your high pressure air compressor.
