1/4-Inch In-Line Pneumatic Pressure Control & Water Trap (JDFF3503) – Heavy-Duty 40 Micron Air Line Regulator | JADEVER

Jadever 1/4″ Industrial Pneumatic Air Filter Regulator (40µm Fiber Filter, 15cc Water Trap Bowl, Integrated Pressure Control, Color Box Edition)

Stop moisture-ruined paint finishes, erratic air pressures, and rusty pneumatic tools before water and grit enter your air lines. The Jadever JDFF3503 Air Filter Regulator replaces basic un-regulated couplings that feed wet, fluctuating compressor air straight into delicate pneumatic equipment. By routing incoming air through a 40-micron fiber filtration membrane and an adjustable pressure regulator valve, this unit supplies dry, clean, and precisely regulated air—giving mechanics, spray painters, and pneumatic technicians a reliable air treatment setup.

40µm Fiber Filtration & Integrated Pressure Regulation

• 40-Micron (40µm) High-Density Fiber Filter Element: Built with a fiber matrix element that intercepts scale, pipe rust, fine dirt particles, and liquid water droplets before they reach air tools or spray guns.

• Integrated Locking Pressure Regulator Knob: Features a top-mounted push-lock pressure adjustment knob. Pull up to adjust and push down to lock your desired operating pressure, preventing accidental pressure drift during long work cycles.

• 15cc Transparent Moisture Inspection Bowl: Molded from chemical-resistant, high-transparency polycarbonate resin, allowing instant visual checks of trapped moisture levels at a glance.

Universal 1/4″ Port Fitment & Pneumatic Line Protection

• Standard 1/4″ NPT/BSP Threaded Port Fitment: Tapped with standard 1/4-inch female threaded ports for easy inline installation right after your air compressor manifold or directly before hose reels and tool drops.

• Bottom Manual Drain Valve: Outfitted with a simple push-turn manual drain valve at the base of the 15cc bowl to rapidly flush out accumulated water condensation without shutting down line pressure.

• Durable Die-Cast Frame Housing: The main body housing is cast from rigid aluminum alloy to withstand everyday workshop line pressures, vibrating compressor manifolds, and rugged shop environments.

Best Use Cases

• Automotive Body Shops & Precision Spray Painting: An essential inline safeguard in garage bays to eliminate water droplets and stabilize air pressure, preventing fisheyes, orange peel, and color unevenness in high-gloss automotive paint jobs.

• Pneumatic Tool Lines & Assembly Workstations: Perfect for running air-powered tools like nailers, staplers, air ratchets, and blow guns at stable, manufacturer-recommended operating pressures.

• Fine Art Studios & Detail Airbrushing: A clean, stable air supply asset for artists using micro-pneumatic airbrushes or fine detail cleaning blowers, preventing moisture spits and pressure spikes during delicate work.

• General Industrial Fabrication & Maintenance: An indispensable utility unit for factory maintenance teams to protect pneumatic cylinders, solenoid valves, and automated air clamps from line debris and pressure surges.

TK Pro Tip: An air filter regulator protects your pneumatic tools, and proper vertical mounting plus daily drainage are key to maintaining dry, stable air pressure! Always install the unit vertically with the transparent bowl facing straight down toward the floor, as gravity is required to pull separated water into the bottom of the catch bowl. At the end of every work shift, open the manual drain valve at the base of the 15cc bowl to flush out accumulated moisture so water never reaches the level of the fiber element. When threading fittings into the 1/4″ ports, apply a few wraps of PTFE thread seal tape—and hand-tighten firmly to avoid cracking the cast housing—ensuring a leak-free air seal across your shop line!

The TK Tools Promise

• Verified: 100% original, factory-authentic Jadever pneumatic accessories—sourced directly and verified for true 1/4″ port threading, genuine 40µm fiber filter media, and authentic 15cc bowl specifications.

• Thread Tolerance & Pressure Seal Bench Check: Because air leaks cause compressor cycle drag, our technical team in Salem manually unboxes sample units, inspects the 1/4″ internal threads, tests the O-ring seals on the transparent bowl under pressure, and checks the smooth operation of the regulator knob and manual drain valve before approving the color box pack for final warehouse dispatch.

• Fast Delivery: Packed securely inside custom shock-absorbent multi-layer cushioning and shipped rapidly from our main central hub straight to your garage counter, industrial shop, or field tool chest.
