The FS-Curtis CA5+ Duplex Air Compressor combines industrial-grade construction with intelligent dual-pump design to deliver 37 CFM at 175 PSI from its 120-gallon ASME tank. This duplex configuration is engineered for shops with varying demand levels, featuring two 5 HP motors driving E57 pumps that alternate during normal operation and run together when peak demand requires maximum output. Available in both single-phase 230V and three-phase configurations (200-208V, 230V, and 460V), this compressor is built to handle automotive, light industrial, and other heavy-duty applications where reliability and uptime are non-negotiable.
Duplex Design: Smarter Air Delivery, Longer Equipment Life
Duplex compressors are ideal when there are varying demand levels during operation. By alternating demand across two pumps, the CA5+ duplex compressor delivers longer pump life and ensures you'll always have air, eliminating maintenance downtime. The redundant pumps mean that even during service on one unit, your shop continues operating without interruption.
The alternator control panel comes factory-mounted with magnetic motor starters and thermal overload protection. During normal operation, the compressors alternate to balance wear and runtime. When system demand spikes, both compressors engage automatically to deliver maximum airflow. This intelligent duplex design reduces electrical costs by running only what you need, while eliminating costly downtime.
Industrial-Grade Construction for Rugged, Heavy-Duty Applications
CA Series compressors aren't just built to handle harsh environments — they're available in a wide range of configurations to meet your exact application. You'll get the rugged construction you desire in the configuration you need.
For automotive, light industrial and other challenging applications, CA Series compressors are built to last. Components are selected based on durability and performance, ensuring that your CA5+ compressor delivers reliable performance in demanding applications. Precision-machined components and a dedication to materials of construction that are meant for real world working conditions further assure long-term durability. Industrial design delivers the most robust air compressor in its class, providing higher pressures, better efficiency, and longer life than entry level models, and making the CA Series ready to handle the most rugged, heavy-duty applications.
The Most Durable Pump Construction Available
Meticulous material selection ensures long-term reliability. The CA5+ features a pump design that prioritizes longevity and consistent performance through premium materials and thoughtful engineering:
