Oil Water Separator Small Air Filter Regulator Corner Nailer – NN35 AFR2000
The oil water separator small air filter regulator corner nailer NN35 is a compact, single-body combination unit that filters moisture and particles from compressed air while regulating working pressure for corner nailer pneumatic systems. Its small footprint makes it ideal for machines with limited installation space or for supplementary filtration in individual circuit branches.
Compact but Complete Air Preparation
Despite its smaller size compared to the NN32 FRL combination unit, the NN35 oil water separator small air filter regulator corner nailer provides two of the three critical air preparation functions: filtration and pressure regulation. The transparent filter bowl allows visual monitoring of accumulated water level without removing the bowl. The built-in dial gauge (0–10 bar / 0–150 PSI) provides continuous pressure display at a glance.
AFR2000 Design Features
The NN35 uses an AFR2000 type body—a widely standardized compact filter-regulator format with a clear polycarbonate bowl, manual or automatic drain, metal die-cast body, and knurled adjustment knob. Push-fit connectors (blue) allow quick, leak-free tubing connections. The elbow connector orientation on the pressure tap allows easy gauge reading from the operator position.
When to Use NN35 vs NN32
Use the NN35 on smaller corner nailers, tabletop nailers, or single-circuit pneumatic systems where a full FRL lubricator unit (NN32) is not required. Also use NN35 as an additional filtration stage on CNC nailers that have already been serviced by a main FRL unit but benefit from secondary filtration before a critical valve. Its compact size also makes it a good retrofit solution when adding pneumatic accessories to an existing machine.
Installation
Install the NN35 in the main air supply line before other valves and cylinders. Mount it in an accessible position for easy bowl draining and pressure adjustment. Connect inlet and outlet tubing to the push-fit connectors. Adjust the knob to the working pressure specified in your corner nailer’s manual (typically 0.4–0.6 MPa for most nailer types).
Maintenance Schedule
Drain the filter bowl daily in humid environments. Replace the filter element every 6 months or when flow restriction or discoloration is noticed. Check O-ring seals on the bowl annually and replace if cracking or leaking is observed. Proper maintenance ensures the NN35 oil water separator small air filter regulator corner nailer delivers clean, regulated air throughout its service life.
Order the NN35 oil water separator small air filter regulator corner nailer from XKY Framing and ensure clean, properly pressurized air for your pneumatic nailer system.
