Y. ` ------------------------------------------------------------- I--J G 1 I H I LJ | ^_PftOOUCT5 ^ Agents in All Principal Cities ------------ ------------------------------------- AGITAIR DIFFUSERS Type R AGITAIR is the only diffuser that offers the higher efficiency of the square or rectangular shape in diffusing air quietly, draftlessly and with rapid temperature equalization throughout the average square or rectangular room. Its patented construction can be assembled into patterns which discharge the re quired amount of air in one to four directions. Each side delivers a quantity of air proportional to the areas served. Thus the engineer or architect can select an attractive diffuser ^that fits his design-- rather than make his design fit the diffuser. Circular AGITAIRS combine beautiful design with finest operating features, to give rapid temperature equalization and draftless diffusion of air. Model CSF is quiet, easy to install. Pressure losses at minimum. Type A diffusers are smaller, weigh less, are easy to install. Type CM is for marine use. In all sizes for all types of mounting and with lighting combinations. ^ Dampers are provided where needed. The AGITAIR Diffuser Data Book, available to architects and engineers, will help you design and install air distribution systems. Consult our engineers. OIL BURNING HOT WATER GENERATQRS Ideal for hot water or heating service in domestic, apartment house, industrial and marine applications because they are light in weight and can be installed without special foundations or floor coverings. The AGIT AIR is down-fired to conserve floor space and facilitate servicing of the burner. Burner is fully automatic, with simplified design to reduce weight, cost of installation and possi bility of'.failure. Special stacks are not necessary. Type A, weight 300 lb, 400 to1000 sq ft radiation. Type B in larger capacities from 1000 to 4500 EDR. Ask for bulletin. 1080 Air Devices, Inc. . Air System Equipment Registers and Grilles AGITAIR AIR FILTERS Permanent, cleanable AGITAIR Air Filters give more effective filtering with greater dust holding capacity and excep tionally low resistance. The new, improved filter medium di vides theair stream into myriadsof streams which impinge upon and deposit dirt and dust on the viscous coated surfaces. Large interstices provide exceptional dust-hold ing capacity--AGITAIR serves longer without cleaning. Ideal for applications where filters are in service for many hours without a "rest" period, because AGITAIR'S viscous coat ing has a vigorous "wick action" that keeps the surface of the dust deposit always wet, no matter how fast the dust cake builds up. Construction is sturdy arc-welded steel, with protected faces to withstand severe cleaning abuse. They are easier to clean, and can be returned to top efficiency with little trouble. Heating, ventilating, and air con ditioning: AGITAIR Air Filters in thicknesses of 1 in. and 2 in. Sizes up to 1200 sq in. Industrial: Heavy-duty AGITAIR filters 2 in. and 4 in. thick. Sizes up to 2400 sq in. AGITAIR engineers have solved many industrial air filtering prob lems, such as protection for heavy blowers and.other equipment. Call on our ex perience. Grease Filters: For kitchens, etc. Capacity cfm. .pier sq in. with fan system; 1 cfm. per sq in. on gravity exhaust. Standard sizes up to 25 x 30 in.; others to 2400 sq in. Complete assemblies available. FILTER HOLDING FRAMES Adaptable to .all types of installations. Saves time and labor, eliminates bolts and rivets in frame,.and minimizes air leakage. Typical Filter Holding Frame Made of heavy steel, assembly is sturdy, neat. Available for all standard and special sizes of AGITAIR filters. V-Type assemblies of AGITAIR filter holding frames are available to increase filter area where space is limited. AGITAIR WIND-ACTUATED EXHAUSTERS Provide proper ventilation regardless of wind direction, and with positive elimination of down-draft. Functions at peak efficiency at average low wind velocities. Will not re strict the flow of air or gases when there is no movement of outdoor air across the head. Available in sizes from 4 in. to 48 in. neck diameter, with capacities shown at right. For calculation of natural .ventilation requirements, and for proper design principles, refer to Chapter 9 of this Guide. Fan-equipped units also for higher ratings. Bul letin EX-101.
