Interstate WR1110 90 PSI Fixed Preset Regulator
The WR1110 is a compact 1/4″ NPT inline regulator designed for steady 90 PSI outlet pressure. Its fixed preset helps maintain constant inlet pressure to connected equipment, reducing tool fluctuations. Built from a high-strength aluminum alloy and anodized for corrosion resistance, this unit offers a slim profile for a clean installation in tight spaces.
Interstate WR1105 50 PSI Fixed Regulator
The WR1105 provides a fixed 50 PSI output ideal for lighter-duty tools and precision applications. It uses a corrosion-resistant aluminum alloy body with a slim profile for straightforward mounting. Inlets accommodate up to 230 PSI, ensuring reliable operation even with fluctuating supply lines.
Interstate WR1115 120 PSI Fixed Regulator
The WR1115 steps up to a 120 PSI preset, suitable for heavier pneumatic tools or equipment requiring higher stable pressure. Like its siblings, it features a robust aluminum alloy body with anodized finish for corrosion resistance and a slim, easy-install design to fit compact mounting spaces.
Co2 Air Shifter Regulator For Racing (Preece Precision)
This regulator is a dedicated CO2 piston model with a fixed 100 PSI setting and a CGA320 cylinder connection using Permaseal to eliminate washers. It uses a machined brass body and 1/4″ FNPT gas outlet, designed for precise CO2 regulation in racing or similar high-demand setups.
VIAIR Inline Regulator 0-200 PSI
The VIAIR inline regulator covers a broad 0-200 PSI range with a locking adjustment dial to fix the set pressure. It includes a mounting bracket and hardware for secure installation, making it suitable for portable or fixed air systems requiring adjustable pressure control.
PRO-EDGE Industrial 94 PSI In-Line Regulator
This preset inline regulator provides a 94 PSI setting with a 1/4″ NPT inlet and outlet, enabling direct connection to air tools. The lightweight aluminum body supports easy handling and installation while delivering consistent performance for standard pneumatic tools.
Qolekog 230 PSI 1/4″ NPT Regulator
The Qolekog regulator offers 1/4″ NPT male threading with a 0-180 PSI operating range and a maximum of 230 PSI. It emphasizes high flow and pressure resistance, making it suitable for demanding air systems requiring higher output without sacrificing stability.
SNS AR2000-N02 0-150 PSI Regulator
The SNS AR2000-N02 provides adjustable pressure up to 150 PSI with 1/4″ NPT threading and a listed flow rating. It includes a compact form factor and a straightforward adjustment mechanism, making it a practical choice for mid-range pneumatic tools and equipment.
Buying Guide: Key Purchase Considerations
- Pressure range and preset accuracy: Choose a regulator whose fixed setting matches your tool requirements while offering stable output vs. supply fluctuations.
- Inlet compatibility and threads: Confirm 1/4″ NPT or other thread sizes match your system and fittings to minimize adapters and leaks.
- Material durability: Aluminum bodies resist corrosion and are lightweight; brass variants are robust for high-flow or rugged environments.
- Size and installation space: Slim, inline designs save mounting space on benches, carts, or tool walls; measure available room before buying.
- Maximum inlet pressure: Ensure the regulator can handle your compressor’s shut-off pressure without bypass or failure.
- Additional features: Locking dials, included brackets, and gauges can improve stability and make future adjustments easier.
- Application suitability: For racing, choose CO2-specific or high-flow models; for workshop tools, opt for midsize ranges with solid durability.
- Maintenance considerations: Look for anodized finishes and corrosion-resistant materials to minimize maintenance and replacements.
When selecting a fixed regulator, align the product’s outlet pressure with the needs of your tools, your system’s inlet pressure, and the physical constraints of your installation space. Durability, ease of installation, and reliability under continuous use are critical for long-term performance in American workshops and garages.
