A new series of 18-inch stir fans is now available. They have two guard options and a single- or variable-speed motor option. The standard VS18 and VS188 models have wide guard spacing to reduce buildup and cleaning time to ensure fans are running at maximum capacity all year long. To satisfy horticultural applications, a white powder-coated, OSHA-approved guard is now available for fans that must be mounted below 7 feet. All fans have a mounting bracket, which allows for simple tilt and swivel.
