DeVilbiss HAF28 Two-Stage Filtration System, Centrifugal & Coalescer with 60 CFM Regulator

DeVilbiss HAF28 Two-Stage Filtration System, Centrifugal & Coalescer with 60 CFM Regulator

• This DeVilbiss HAF28 two-stage filtration system is designed to condition compressed air by removing water, oil and fine contaminants before painting applications; it features a centrifugal first stage and a coalescer second stage, coupled with a 60 CFM regulator.
• Features:
  • First-stage centrifugal filter removes bulk water, oil and dirt down to approximately 0.5 microns, providing cleaner air for downstream stages.
  • Second-stage coalescer filter refines the air further by removing oil, water and particulates down to approximately 0.01 microns for high-quality spray finish performance.
  • Integrated regulator rated at 60 cubic feet per minute (CFM) allows precise downstream pressure control in applications such as spray painting or automotive refinishing.
  • Compact single-unit assembly simplifies installation compared to separate filters and regulator models, reducing footprint and improving ease of maintenance.
• Includes:
  • Stage 1 centrifugal filter assembly (housing, bowl, element)
  • Stage 2 coalescer filter assembly (housing, bowl, element)
  • 60 CFM regulator (pre-mounted to filter assembly)
• Specifications:
  • Manufacturer: DeVilbiss Automotive Equipment Co.
  • Part Number: HAF28
  • Filtration: Two-stage (centrifugal + coalescer)
  • First-stage removal: ~0.5 microns
  • Second-stage removal: ~0.01 microns
  • Regulator flow capacity: 60 CFM
  • Application/Compatibility: For compressed-air systems in automotive paint and refinishing environments requiring clean, dry air.
• The HAF28 filtration system can also be referred to as DeVilbiss HAF-28 two stage air filter regulator, DeVilbiss Clean-Air HAF28, automotive paint air filtration HAF28 kit, and DeVilbiss 60 CFM filter regulator combo HAF28.

The DeVilbiss HAF28 is a professional-grade compressed-air filtration system combining centrifugal and coalescing filtration with a built-in 60 CFM regulator, engineered for automotive spray finishing and industrial applications where air quality directly impacts finish quality.

Q: Can I use the HAF28 system without the regulator connected?
A: No; the system is supplied as a combined assembly where the regulator is mounted and sized for the unit’s performance. Omitting the regulator could degrade precise pressure control or impair the system’s intended performance.

Q: What maintenance does the HAF28 require and how often?
A: Replace the filter elements when monitoring indicates increased pressure drop or when water or oil carry-through appears. The centrifugal bowl should be drained regularly to remove collected water before it reaches the coalescer stage.

Q: Is the HAF28 suitable for general shop airflow (e.g., 300 CFM) systems?
A: The HAF28 is rated at approximately 60 CFM regulator capacity; for substantially higher flows you should evaluate a larger-capacity filtration/regulator system to avoid restricting airflow or creating excessive pressure drop.
