Mist Collector: Spiral Tube

Spiral Tube Mist Collector

System Design
The Monroe Spiral Tube Oil Mist Collector is a two stage unit and does not require filter media for primary mist removal.

The spiral tubes provide a high level of mist agglomeration and removal without using filters. Centrifugal force and impaction provide the mechanism for mist removal.

Dirty air is propelled down several spiral shaped impaction tubes and a fluid film is created. The oil drains into the collector bottom. Air changes direction 180 degrees, then enters the second stage HEPA type filter typically rated at a minimum 95% efficiency at 0.3 micron particle size.

Ideally suited for production machining operations with water soluble, synthetic or mineral coolants.

Oil Re-entrainment Eliminated
Due to the unique internal design of the Monroe collector, the cleaned air will not re-entrain collected pollutants after the primary stage. This improves the efficiency of the separation process and extends the life of the optional final filters.

High Efficiency
The advanced design of the Monroe Spiral Tube Collector provides maximum mist and oil collection efficiency in a mechanical collector. Air processed by the Monroe Spiral Tube Collector meets air quality standards for in-plant discharge as well as outside exhaust. Discharging clean, filtered air back into the work area can significantly reduce climate control costs.

Materials of Construction
The Monroe Spiral Tube Collector features heavy gauge mild steel and stainless steel construction for years of efficient performance. Welded seams and built-in lifting hooks provide rugged durability.

HEPA Type Filters
The Monroe Spiral Tube Collector is available with specially constructed HEPA type fiberglass filter cartridges as the optional final filter system. These filters are normally supplied with a 95% efficiency rating at 0.3 micron. Final filters have a long service life because the majority of airstream contaminants are removed by the spiral tube stage. Slide-out design for easy filter removal is included.

Special Features
Large, easy to open access doors for all serviceable areas.

An AMCA rated fan on the outlet side of the collector with either a direct coupled motor or a "V" belt drive.

Quiet operation. Rubber isolation fan connection and sound attenuators are available if needed. Under 80dba is typical.

Integral differential pressure gauges are available to indicate when filter maintenance is required.

Complete electrical controls are available to meet customer specific requirements.

Many Configurations Available
Monroe Spiral Tube Collectors can be configured to meet specific needs with numerous options available to provide maximum efficiency in any application.
