PowerBreather – CVTM

The PowerBreather-CVTM unit is a marked improvement over the customary dust caps or OEM breathers on equipment. When contaminated air enters the top of the breather, it passes through layered filter media, preventing solid particles from entering the breather and causing undue wear to your equipment surfaces. Filtered air passes through a bed of PowerBreatherTM silica gel, which removes harmful moisture from the air. The silica beads also work to attract moisture from inside the equipment reservoir during service or shut-down, keeping the equipment dry. The addition of check-valves in our CV breather is ideal for low-flow and intermittent operations in high humidity conditions.

Product Breakdown

1. Center Tube

The center tube is constructed from rugged nylon material providing rigidity to the element and allowing for even airflow through the silica gel.

2. Secondary Filter Media

Second filter step prevents any possible migration of silica dust providing added system protection.

3. Oil Mist Collector

Polyurethane foam collects oil mist and distributes air evenly over filter media and moisture absorbing silica gel.

4. Moisture Absorbent

The PowerBreatherTM silica gel provides industry leading moisture removal and holds up to 40% of its weight.

5. ABS Outer Shell

Clear outer shell provides a visual indicator of silica gel condition allowing for optimum change out intervals.

6. Filter Media

3-micron absolute particulate filtration is provided by a polyester filter media.

7. Check-Valves

Check-valves provide protection in wash down areas. Check-valves isolate equipment from ambient conditions, prolonging life.

8. Sure-fit Connection

Use sure-fit connections instead of filler/breather cap. Adapters also available.
