NANPU 3/4″ NPT Industrial Grade 3 Stage Air Drying System
The NANPU system features a three-stage process including a particulate filter with a 5 micron element, a coalescing filter with a 0.01 micron element, and a desiccant stage. It operates effectively under 30-175 psi, with a metal bowl and a visible sight glass for safety and easy monitoring. An auto drain helps reduce maintenance, and the stage 2 indicator warns when the filter needs replacement.
Key details include a 141 CFM (4000 L/min) flow rate capability and a robust metal bowl designed to withstand demanding industrial environments. The combination targets moisture, particulates, and oil within paint spray and plasma cutting workflows.
3/4″ NPT Industrial Air Dryer For Compressor (3 Stage)
This three-stage air drying system handles high-pressure environments up to 240 PSI. It uses a 5 micron initial filter to remove moisture and debris, a 0.01 micron agglomerated filter for the remaining contaminants, and a desiccant stage to ensure exceptionally clean, dry air. A green indicator confirms when a stage requires replacement, and a visual window helps with maintenance planning.
The unit supports rugged industrial applications with dual 3/4″ NPT air ports and a 1/4″ NPT gauge ports, making it suitable for paint spray and plasma cutting workflows where reliability is essential.
3 STAGE Heavy Duty Filter Regulator Coalescing Desiccant Dryer System (1/2″ NPT)
Edge Industrial’s 1/2″ NPT unit integrates a water trap filter, pressure regulator, coalescing filter, and desiccant dryer, all in a compact package with a wall-mount bracket and an auto drain. Stage 1 uses a 5 micron element to remove most moisture and debris. The regulator covers 7 to 175 PSI, and the metal bowl includes a sight glass for quick status checks. This system is designed for paint spray and plasma cutting lines needing reliable air dryness.
NANPU Industrial Grade Heavy Duty Desiccant Dryer (1/2″ NPT)
This NANPU model focuses on thorough drying and cleaning of air before it reaches pneumatic tools. It includes a metal bowl with a sight glass and uses desiccant beads that indicate renewal by color change (blue to pink). It is suited to paint spraying and plasma cutting setups, with a pressure range of 7-215 psi, ensuring compatibility with typical shop compressors.
Schulz Refrigerated Air Dryer (50 CFM) With Pre-Filters
Schulz refrigerated dryers deliver low dew points for oil-free, moisture-free air suitable for larger compressors. This 50 CFM unit includes industrial-rated water separation and oil removal coalescing filters. It is essential for environments where consistent, ultra-dry air is required, like high-precision painting or plasma processes. Dew point targets and maximum inlet pressures should be matched to the system requirements to avoid filter saturation.
3 STAGE Heavy Duty Industrial Grade Filter Regulator (3/4″ NPT)
This 3/4″ NPT system provides robust air treatment with stage 1 water trap/pressure regulator, stage 2 coalescing filter (5 micron), and stage 3 desiccant dryer. It features a wall-mount bracket and an auto drain, with a 175 PSI max input and a 5 micron initial filter to remove moisture and debris. The 5oz metal bowl with a sight glass allows for quick visual inspection during operation.
Buying Guide
- Port size and pressure range: Ensure the unit offers the correct NPT size and supports your system’s operating pressure. Higher PSI capacity is beneficial for heavy-use environments like plasma cutting and spray painting.
- Filtration stages: Multi-stage systems (5 micron + 0.01 micron) remove both moisture and fine particulates. Desiccant stages achieve extremely dry air, which is critical for tools and finishes sensitive to moisture.
- Indicator features: Visual sight glasses and color-changing desiccant beads simplify maintenance planning and reduce downtime.
- Maintenance access: Auto drain features and accessible filter housings save time on routine servicing.
- System compatibility: If multiple tools share the same line, choose a unit designed for consistent output and stable pressure regulation to avoid cycling or pressure drop.
- Safety and durability: Metal bowls with sight glasses enhance safety and provide long-term reliability in industrial settings.
- Application fit: For paint spray and plasma cutter workflows, prioritize units with proven performance in removing oil, moisture, and particulates to ensure a pristine air supply.
