Air Regulator Speedaire 4ZM23 3/4 in NPT 220 CFM 300 PSI

Description

Product Overview

The Speedaire 4ZM23 air regulator is engineered for reliable pressure management in a wide range of compressed‑air applications. Featuring a 3/4 in NPT inlet, it delivers a maximum flow of 220 CFM at pressures up to 300 psi, making it suitable for both high‑demand industrial machinery and smaller workshop tools. Constructed from durable metal components, the regulator resists corrosion and wear, ensuring a long service life even in harsh environments. Its compact dimensions—7.2 × 3.5 × 3.4 inches—allow easy integration into tight spaces, while the precision‑machined valve provides smooth, repeatable adjustments. The product meets ISO standards for safety and performance, and it carries the Speedaire brand reputation for quality pneumatic solutions.

Usage

Designed for versatility, the 4ZM23 regulator excels in a variety of settings. In manufacturing plants, it stabilizes air pressure for CNC machines, robotic arms, and pneumatic actuators, preventing fluctuations that could cause downtime or equipment damage. In automotive workshops, the regulator ensures consistent airflow to paint sprayers, impact wrenches, and tire inflation stations, improving tool efficiency and operator safety. Portable applications such as field‑service compressors benefit from the regulator’s lightweight design (0.01 oz) and easy‑to‑install NPT connection, allowing technicians to quickly set up reliable air delivery on site. The regulator also works well in laboratory environments where precise pressure control is essential for experiments involving pneumatic instrumentation.
