Oil Bath Air Filters

Oil Bath Air Filters for industrial machinery and endothermal engines.

Oil Bath Air Filters are mostly used on industrial machinery, endothermal engines especially working in very dusty environments or whenever you want to best preserve machine and guarantee its long lasting life cycle.
The intake air moves toward the oil bath in the tray, then goes up through the 2 AR metallic mesh cartridges that clean the air optimally.

Maintenance operations for oil bath air filters consist of periodical check (it depends on the use conditions) of the level and the quality of oil. In case of negative result, oil shall be emptied and replaced after washing the tray and the movable filter elements.
We start from OT/60 and OT/65 moplen (plastic material) models to steel, carbon, powder-coated models or those treated to resist to environments rich in acids. Infinite variants and customisations for Oil Bath Air Filters (iron filter cap, prefilters, air inlets/outlets position, drawing processes) therefore we suggest you to contact us for any special requirement. The filter case itself may be designed for dry air filtering with pleated filter elements.

Pre-cleaners for oil-bath air filters.

By removing the larger contaminant particles, these pre-cleaners will not only reduce maintenance on these costly air filters, but they will also cut machine stoppages to a minimum while simultaneously extending engine life.

Seated pre-cleaner. Seated pre-cleaners combine an excellent degree of filtration with smaller overall dimensions, because the vortex unit rests on the
filter body. This is the ideal option for areas with large amounts of dust.

Detached pre-cleaner. Detached pre-cleaners take their name from the fact that they are separated from the filter body. They can be made from plastic material for the following sizes: Ø 35, 42, 45, 50 and 60 mm; or from iron for the following diameters: Ø 57, 63, 65, 67 and 76 mm. Both versions have fins, so as to impart centrifugal force to entering air, which ensures that the contaminants are deposited.
