RDHL Desiccant Heatless Series

Rated at -40°F (-40°C) dew point at 100 psig (6.9 bar), these dryers are mounted on draggable skids with air-in, air-out out, and power connections. Their rugged design makes them well-suited for the punishing rental industry. Pre-filter with DP gauge protects desiccant bed from oil and particulate contamination. After-filter with DP gauge removes dust and desiccant fines from the final air system.

Models vary by region. Please contact your Sullair sales representative for more details.
