AirTAC GFR400-15-A-F1 Filter Regulator (1/2", Automatic Drain, Square Gauge)

## Product Overview

The AirTAC GFR400-15-A-F1 is a premium, high-flow integrated filter and pressure regulator belonging to AirTAC’s next-generation Green Series (G Series). This flagship 2-in-1 workstation provides space-saving, dual-function compressed air treatment by combining an advanced centrifugal moisture separator with a high-precision, balanced pressure regulator into one single heavy-duty aluminum alloy body.

Featuring a factory-installed automatic drain system (-A) and an elegant embedded square pressure gauge (-F1), this specific configuration represents the pinnacle of operator convenience and system automation in modern pneumatic setups.

## Key Features & Technical Highlights

• Space-Saving Embedded Square Gauge (-F1): Unlike traditional bulky round pressure gauges that stick out and are prone to accidental breakage, the GFR400 features a flush, embedded square faceplate gauge scaled in MPa. This significantly reduces the unit's physical envelope and installation depth.

• Fully Automatic Drainage (-A): Eliminate manual maintenance routines. The internal auto-drain floating mechanism detects moisture levels and automatically expels condensation once it reaches capacity, protecting downstream components even in 24/7 unmanned operations.

• Press-In Self-Locking Mechanism: The top pressure adjustment knob features an ergonomic push-to-lock design. Simply pull up to tune the pressure, and press down to lock it securely, preventing setting drift caused by machine vibrations or external interference.

• Balanced Pressure Regulation: The internal regulation mechanism relies on a highly responsive balanced design. This layout ensures extremely stable output pressure with minimal pressure hysteresis, even when the inlet pressure fluctuates wildly.

• Centrifugal Diversion Structure: Air entering the bowl is forced into a high-speed spin by a specialized directional vane structure. This maximizes centrifugal liquid separation before the air passes through the 40-micron solid particle element, ensuring optimal water removal efficiency.

## Important Buying Guide: Selecting the Right Thread Standard

To ensure a seamless drop-in installation, please double-check your system's piping thread requirements before placing your order. We offer three variations of the GFR400-15-A-F1:

1. Standard Version (PT Threads): The baseline model. Uses British Standard Taper Pipe threads (equivalent to Japanese JIS R/Rc threads). Perfect for machinery sourced from Asia or Japan.

2. "-G" Suffix Version (G Threads): Uses European parallel straight threads (BSPP). Standard for most European industrial automation networks.

3. "-T" Suffix Version (NPT Threads): Highly recommended for customers in North America (USA & Canada). All 1/2" main ports are tapped with American National Standard Taper Pipe Threads, allowing you to connect local brass or steel fittings directly without leaks or thread stripping.
