Automatic Air Discharge. Standard traps automatically discharge normal amounts of air along with condensate. Where large amounts of air must be vented quickly when steam is first turned on, Armstrong BLAST Traps with thermic bucket vents are recommended. Air handling capacity ranges from 500 to 1500 cu ft free air per hour. NEW! Traps with integral strainers save fittings, labor. No. 880 with same capacity as No. 800listed belowis$11.50. No.881 with same capacity as No.811 is $16.00. Both cost less than traps plus separate strainers. No. 800-815 No. S11-Z16 No. 880-881 Side Inlet Traps Pipe Connections.............................

Compact Size. The high leverage of the patented free-float ing lever makes it possible to open dis charge orifices which are very large for over-all trap size. Positive Action. The discharge valve is either wide open or closed tight. Fast opening and closing prevent wire-drawing. Seif-Cleaning. Swirling action of con densate during discharge carries dirt through trap. There are no dead spots for dirt to collect. High Quality. 18-8 stainless interior arts. Valve and seat are chrome steel, ardened, ground and lapped. Low pressure trap parts same material and quality as those used for 1500 psi, 900 F. Armstrong Steam Trap Book. 36 pages of data on traps, selection, instal lation and maintenance. A usable hand book for any engineer dealing with traps. Free copy on request. TRAPS FOR UNIT HEATERS Armstrong inverted bucket steam traps are particu larly suitable for draining low or high pressure unit heaters to vacuum or gravity return systems for the following reasons: 1. Air and CO* are vented automatically every time A the trap opens--this keeps heaters hot, helps pre? vent corrosion. 2. Condensate is discharged at steam temperature as rapidly as it accumulates--keeping heaters at max imum temperatures. 3. Leakage of steam through an Armstrong trap in proper working condition is impossible... no ' build-up of back pressure in return lines. 4. The dependability of Armstrong traps is outstand ing--they seldom require maintenance. A New Bulletin containing Btu output figures for 24 makes of unit heaters explains fully how to select traps for this service. A valuable^compilation that is available to anyone upon request. ARMSTRONG STEAM HUMIDIFIERS For Stores, Offices, Hospitals, Factories, Laboratories Operation. These units provide auto matic, closely con trolled humidification by - introduction of steam directly into the atmosphere. In stallation is compara ble to that of unit "heaters. Steam at 15 psi or less is required. A solenoid discharge valve on the hu midifier is controlled by a sensitive humidistat. A fan mounted on the humidifier'aids in steam dispersal, or a venturi nozzle can be supplied. Where an electric spark might represent an ex plosion hazard, compressed air operated models are available. In addition to the unit humidifier illustrated, there is a large model for installation in large air ducts and central heating systems. Capacities range from 31 to 630 lbs of steam per hour. Advantages. Installation cost of Arm strong Humidifiers is as much as 80 per cent less than.some types of equipment. The small C-2 unit lists at $182.25 com plete with fan and motor, humidistat, strainer and steam trap. Operation, us ing steam at around $1.00 per ton, is economical. There is no extra load on the'heating system. No dripping--any moisture in the steam is re-evaporated in the steam-jacketed separating cham ber. Control is accurate within a few per cent R. H. Bulletin No. 1772 gives complete data on required relative humidities, selec tion .and installation of Humidifiers. All Armstrong products are sold on a basis of satisfaction or your money back. 1379
