MICROFILTERS (M1, M2)

The concept of “low flow: long life” has been the mantra for SANPAR rather than “high flow: short life” while designing and selecting its filter cartridges. The lunatic adherence to this concept is in accordance with the tagline of “energy conservation in compressed air treatment” of SANPAR. This philosophy has stood in good stead when it comes to customer delight and their retention.

These cylindrical filter elements are mounted in aluminum pressure die cast housings or carbon steel housings when it comes to employing multiple cartridges to cater to the higher air flows. While the filtered air conforming to the standards of ISO 8573.1 class 1 for dust and class 1 for residual oil content is lead to the outlet of the housings, the unwanted oil is drained out at the bottom of the housing through a no loss of valuable compressed air drain, which could be float type or liquid level controlled type or electronic timer based drain solutions

SANPAR manufactures micro filters essentially in 5 categories:

PRIMARY PRE FILTER :
SERIES : PPF :
These filters use ss 316 woven pleated mesh to filter particles up to 25 microns.

PRE FILTER :
SERIES : PF :
These filters use cellulose acetate as filtering media and filters particles up to 3 microns.

AFTER FILTER :
SERIES: AF:
These filters use borosilicate glass fibre to filter dust particles up to 0.1 micron and oil particles up to 0.1 mg/m3.

FINAL FILTER :
SERIES : FF:
These filters use borosilicate glass fibre to filter dust particles up to 0.01 micron and oil particles up to 0.01 mg/m3.

ACTIVATED CARBON FILTER :
SERIES : AC :
These filters use the most versatile material activated carbon to adsorb to oil vapour up to 0.003 mg/m3.


Accessories for compressed air filters :

Differential pressure gauge:
These filters are adequately equipped with differential pressure gauges and indicators to ensure that filter cartridges are replaced not too early ; not too late which saves energy.

Drains
Each filter is supplied with an automatic drain to drain off the unwanted oil at the bottom of the housing through a no loss of valuable compressed air drain, which could be float type or liquid level controlled type or electronic timer based drain.

Condensate Level Indicator
This enables to have a visual inspection of the condensate accumulated at the bottom of the filter. This monitors the drain’s performance or to know when to drain-off, if in case the manual drain is fitted.
