AND

INDUSTRIAL

POSITIVE DISPLACEMENT (SLIGHTLY RECUPERATIVE) AND NONRECUPERATIVE

Locomotive style: Make it your self using single acting BIKE PUMP and sliding valve

  • bicycle store part (they'er sold in some GROCERY STORES)
  • air conditioning friendly
  • harder to mount
  • CHEAP!!! $15

    Locomotive style INDUSTRIAL:Stainless steel

  • some mount parts available (interface to wheel still difficult)
  • neoprene seals (A.C. friendly ?)

  • GUARENTEED
  • CHEAP (but harder to get) $15-$45

    Rotory: Probably the best technology altho.....

  • HIGH RPM-20,000rpm
  • some mount parts available (interface to wheel still difficult)
  • long life PROVIDED you do some machining

  • the airplane motors need different BEARINGS and seals (at least!)
  • VARITY-model airplane engines

    these engines range from single piston to 4 cylinder V.W. replicas and the

    WANKLE (think Mazda RX-7) which is my choice!
  • Model ROTORYS ARE PRICEY $45-$350

    Non Recuperative type

    Die grinders and the like
  • cheep $19-$55 (shopping pays!)
  • same mounting problems
  • hi rpm,short life (a real "type A")
  • you cannot breath the exhaust

    Industrial "AIR MOTORS" (cataloged in PNEUMATICS)

  • stall proof
  • gear box can be had (for a price)
  • heavy
  • you cannot breath the exhaust
  • A 1/2 h.p. @5000 rpm consumes around 9 qfm @ 20 psi and only gives 2 in.LB. torque!
  • $120 base -$300 w/gearbox (1/2 hp)
