RMF desiccant breathers
RMF desiccant breathers replace the standard dust cap or OEM breather cap on equipment, offering better filtration to protect against even the smallest particulates. As air is drawn into equipment through the breather, the air filter removes solid particles while the ZR gel granules remove harmful moisture.
For optimal performance of your equipment, hydraulic and lubricating oils should be kept free from solid and water contamination. However most fluid reservoirs must breathe to function, allowing water vapour and solid contaminants to enter. Temperature fluctuations in the reservoir will cause this water vapour to condense which will not only cause oxidation of the oil, but can also lead to considerable mechanical damage.
Filtration and dehydration: a single process
Standard air breathers remove some of the solid particles, but allow water vapour to pass freely. RMF desiccant breathers (also known as RMF air conditioners) deal effectively with both particle and water contamination. The air is dried by passage through a column packed with ZR gel granules. The dried air is subsequently filtered with the use of a pleated synthetic fibre filter element (replaceable spin-on type) that removes solid particles (down to 3μ). This process prevents contamination and oxidation of the oil and components, resulting in a prolonged service life of the oil and equipment and less down time. Reducing the total cost of ownership for your equipment.
Serviceable and non-toxic
All RMF desiccant breathers are completely serviceable. Due to the humidity indicator granules it is very easy to monitor the saturation status of the ZR gel granules. The indicator granules change colour, turning form ruby-red (active) to a light orange (replace). Refills of the non-toxic and non-carcinogenic ZR gel granules are available. The performance of the synthetic fibre filter (spin-on) can also be monitored by an optional ‘filter minder’. A wide range of spare parts is available.
RMF desiccant breathers can be fitted with a combination of ZR gel granules and active coal. This activated carbon will eliminate the oil smell and vapour. Besides this it will prevent the ZR gel granules from being contaminated with oil damp.
Optional check valves can be added for dehydration of gearbox applications. These spring loaded (0,01 bar) check valves are fitted in opposing directions, opening only whilst inhaling or exhaling. This prevents atmospheric contact between the air and the ZR gel granules under static conditions, increasing the lifetime of the drying agent.
The desiccant breathers are compatible with almost all hydraulic and lubricating fluids applications, because of the wide variety of mounting plates.
