Patterson RM18A is a high-velocity ceiling-to-floor air mover designed for demanding factory, warehouse, and distribution-center environments. With a compact 18-inch propeller and a rugged construction, this unit is built to deliver strong air flow across long distances to improve ventilation, reduce humidity buildup, and help maintain a cooler, more comfortable workspace for personnel working in aisles, pick modules, and staging areas. The design incorporates a patented Venturi barrel and side air inlets to project and entrain air efficiently, extending reach while minimizing energy use in continuous-duty applications.
Constructed for durability, the RM18A features a high-impact polypropylene housing combined with heavy-gauge steel components and OSHA-compliant finger guards for safety. The unit uses maintenance-free, direct-drive motors with long-lasting sealed bearings and offers multiple voltage options (115V–460V) to fit a variety of electrical configurations. Its 12-foot power cord (115V only) and eight mounting options provide flexible installation in fixed locations or at different heights and orientations, with optional oscillator kits to broaden the reach of conditioned air.
Ideal use cases include improving air circulation in aisles, workstations, shipping zones, and confined spaces where personnel sufficiency and condensation control are concerns. The RM18A is designed to deliver substantial air movement—up to 3,800 CFM with a 80-foot air throw in appropriate setups—while maintaining a reported operating sound profile appropriate for factory floors. When selecting this unit, consider the electrical supply, mounting flexibility, and whether an oscillator accessory is needed to optimize coverage for your specific space.
