ComfortVUHDiffuser Selection & Heat CoverageWithout DiffuserVUH heaters are usedwithout a diffuser where astraight downfl ow air patternis required. However,any diffuser can be addedto the basic heater.Vertical Delivery Blower Heater (cont’d.)RadialVUR increases fl oor coverage. Hasadjustable fi ns which, when turned toa vertical position, direct air downwardin a pattern tighter than that of a heaterwithout a diffuser. The heater can bemounted 15 to 20% higher than a heaterwith no diffuser, and will still maintainthe same coverage at fl oor level. Conversely,when the fi ns are tilted to a 45°angle, fl oor coverage of warmed air isup to 25% greater (than no diffuser) atrelatively low mounting heights.ConeVUC permits lowmounting of theheater. Throws airoutward over largearea rather thandownward. Conecan be lowered orraised to changethe air fl ow pattern.LouverVUL permits directional(straight line) air fl ow suchas in air curtain applicationsover doorways. Givesrectangular coverage.Louvers can be turned ineither direction.AnemostatVUA “comfort”diffuser givesdraft-free airmovement atlow mountingheights. Floorcoverage is sameas heaters withno diffusers.Diffuser — SpecificationsRadial Cone Louver AnemostatHeater Model AWt.(Lbs.) Model A BWt.(Lbs.) Model A BWt.(Lbs.)
