Overview
The SPXFlow HMD20-3 is a membrane-based compressed air dryer engineered for cost-effective moisture removal in pneumatic applications. Unlike desiccant dryers, membrane technology eliminates ongoing consumable costs and maintenance, making it ideal for facilities requiring steady-state drying with minimal operational overhead.
Key Features
- Desiccant-free membrane technology requires no cartridge replacement
- Compact footprint (15.3″ L × 4.2″ W) suitable for space-constrained installations
- Low energy consumption with no moving parts to maintain
- Rated capacity of 8.7 SCFM at 100 PSIG inlet pressure
- Suitable for general industrial pneumatic systems and light to moderate drying demands
Technical Specifications
- Flow Capacity: 8.7 SCFM @ 100 PSIG inlet
- Maximum Inlet Pressure: 175 PSIG (12 bar)
- Drying Technology: Membrane (non-desiccant)
- Length: 15.3 inches
- Width: 4.2 inches
- Outlet Dew Point: Dewpoint depression dependent on inlet conditions and flow
- Manufacturer: SPX Flow (formerly Hankison International)
- Series: HMD (Hankison Membrane Dryer)
Typical Applications
The HMD20-3 is suitable for:
- General manufacturing pneumatic tool operation
- Instrumentation and control air systems
- Paint and coating application lines
- Small to medium compressed air networks where low to moderate drying is required
- OEM equipment requiring integrated air treatment
Compatibility & Replacements
Compatible With
- Standard compressed air piping systems (1/4″ NPT, 3/8″ NPT inlet/outlet connections)
- Industrial air compressors rated up to 175 PSIG
- Pneumatic tool and instrument networks
- Refrigerated and cycling dryers (as point-of-use secondary drying)
Replaces / Drop-In Replacement For
The HMD20-3 is part of the SPX Hankison HMD series. Related models in the series include HMD20-5 and HMD20-6 variants with higher flow ratings. Direct replacement compatibility depends on connection size and flow requirements—consult the product manual or SPX Flow technical support to confirm interchangeability with legacy Hankison units.
Works With
- SPX Flow Hankison filtration and air treatment product line
- Standard industrial compressed air quality standards (ISO 8573-1)
- Systems requiring Class 3 to Class 4 dew point performance
