Float drains are essential for maintaining the efficiency of compressed air systems, particularly when used alongside air-cooled aftercoolers. As compressed air cools, moisture condenses into liquid water, which accumulates in separators, filters, or receiver tanks. Float drains automatically remove this liquid without wasting compressed air, using a mechanical float mechanism that opens a valve when water levels rise and closes when drained. This prevents water from entering downstream components, protecting against corrosion, contamination, and reduced performance in applications like pneumatic machinery, automotive painting, or food packaging.

Crafted from durable materials such as stainless steel or high-grade aluminum, our float drains are built for longevity and minimal upkeep. They incorporate precision-engineered float valves and robust seals to ensure reliable operation under varying pressures and temperatures. Available in zero-air-loss and standard configurations, these drains cater to both high-efficiency industrial systems and cost-conscious setups. Their compact, lightweight design facilitates easy installation in stationary or mobile compressed air systems, serving industries from construction to manufacturing.

Enhanced features include corrosion-resistant coatings, customizable connection types (NPT, BSP, or flange), and low-maintenance designs that reduce downtime. Optional accessories like drain alarms, visual indicators, and high-pressure models provide added functionality for critical applications. Compliant with industry standards like ASME, our float drains deliver consistent performance, ensuring clean, dry air to optimize compressor system reliability and longevity.

Zero-Air-Loss Float Drains

Zero-air-loss float drains use advanced float mechanisms to expel water without releasing compressed air, maximizing energy efficiency. These models are perfect for continuous-operation systems, such as large-scale manufacturing or remote compressor setups, where minimizing air loss reduces operational costs. Features include self-cleaning valves and optional monitoring systems for enhanced reliability.

Standard Float Drains

Standard float drains offer a cost-effective solution with a simple float valve for automatic water removal. Ideal for smaller compressors or intermittent-use applications, these units are easy to install and maintain, making them suitable for workshops, construction sites, or smaller industrial facilities where manual oversight is practical.
