Heating Systems specialties' Armstrong Machine Works ReprtnitftlTes 851 Maple Street Three Rivers.Mich. Principal cities _ Armstrong offers two types of traps for heating, air conditioning, and steam distri bution service. Standard Inverted Bucket Traps, the type originated by Armstrong, are non airbinding and self-scrubbing. They are used for Tow, medium, and high pressure service where relatively little air must be handled along with the condensate. Their free-floating lever design makes it possible to open very large discharge orifices com pared with the size of the trap itself. Armstrong Blast Traps are used where large amounts of air must be vented quick ly when steam is first turned on. They have several advantages over the conven tional float and thermostatic trap. 1. The Armstrong Blast Trap has but a single orifice to be maintained tight agarfist the full pressure differential. 2. Positive action. The discharge valve in an Armstrong Blast Trap is either wide open or tight shut. Fast opening and fast closing prevent wire-drawing. 3. Handles dirt. There are no dead spots in an Armstrong Trap in which dirt can settle and interfere with the operation of the trap.

It also contains 17 pages of data on the subject of trap selection, installation, and maintenance. A free copy will be mailed on request. AIR VENT AUXILIARY ^YENT FOR BLAST TRAP JOBS ALL Armstrong traps are readily convertible into "Blast" type traps merely by using buckets equipped with the patented auxiliary thermic air vent. As shown in the above sketchy, the mechanism for this vent consists of a stainless steel disc slotted to receive the end of a bi-metal strip. Different coefficients of expansion in the bi-metal cause it to bend down when cold and up when hot. Normally, it is set to close at 212 deg, but it can be set to close at higher temperatures. Capacity, 50 to 100 times the air-venting capacity of a standard trap. Bottom Inlet Traps Trap Size' No. 211 Pipe Connections....... List Price (Regular)..
