2. New Bellow Breather – Isolates equipment from the atmosphere –Application for bellow breather in industry »Pumps, fin-fan gearboxes, oil reservoirs, power transformers etc. »In areas where moist, dust in the form of coal and sand is a source of contamination of the lubrication oil this breather will stop ingress and add quantum life to machinery.

3. 3 Components of bellow breather 80 mic Filter at Breathing opening Breathing opening Bellow or bladder One way valve releasing at +1000 Pa Sight glass for silica gell Demister section 10 mic Filter Connection for; Pump, gearbox, oil reservoir, transformer etc.

4. 4 Features The air leaving the rotating equipment contains water vapour and also oil is sometimes splashed out the vent point. The purpose of the demister section is to prevent the oil drops to reach the filter membrane and clogs the pores. The water vapour will go through the demister section and will be absorbed by the absorbent granules. As the equipment breath during heat cycles the inner moist is absorbed by the absorbent material.During the breathing stage the equipment remains totally isolated from the atmosphere. This is been achieved by the bellow moving up and down to allow for volume changes.
