Wright Austin/Eaton - Float Drain Traps
Gas/Liquid Exhaust Heads

Eaton Type 40 Exhaust Heads are designed to separate entrained water and oil from exhaust air, gas, or steam prior to being discharged directly into the atmosphere. They remove more than 99% of liquids and solids over 10 microns in size from the discharged flow, reducing maintenance costs on roofs and surrounding objects.

Operation
Moisture-laden gas, air, or steam enters at the inlet of the exhaust head where it is directed into a centrifugal upward motion. The entrained solids and moisture droplets are separated out by a reduction in velocity and fall into a drain reservoir.

Type 40EHC Rugged Cast Iron Construction
The Eaton Type 40EHC Exhaust Head is designed for long service life. Its body, cover and separating elements are made of high tensile strength cast iron. Sizes 3” and smaller have threaded NPT connections. 5” and larger have 125 lb. flanged connections. Size 4” models can be ordered with flanges or threads. The flange bolt holes are drilled to straddle the center line of the drain outlet. Flanges are cast integral with the body and have slotted holes, which are recessed to prevent the bolt heads from turning.

Type 40EHMF Fabricated Carbon or Stainless Steel Construction
The Eaton Type 40EHMF Exhaust Head is welded at all joints to withstand heavy duty usage. These exhaust heads work at high temperatures and remain efficient even when steam or gas is discharged at high velocities. The Type 40EHMF has been designed to minimize the noise associated with high discharge velocities.

The units permit free flow of steam, gas or vapors with an absolute minimum of back pressure. They feature a separating element of 304/304L stainless steel, and the entire exhaust head can be ordered in 304/304L or 316/316L stainless steel if required. Type 40EHMF (Fabricated) Gas

Features
  • Choice of Cast or Fabricated Construction
  • Removes 99% of Liquid and Solid Entrainment Particles Larger Than 10 Micronss
  • No Required Maintenance
  • Highly Efficient
  • Virtually No Back Pressure
Cast Iron - Type 40EHC

Wright Austin cast iron exhaust heads are designed for long service life, the body, cover and separating element are constructed of high tensile cast iron which resists fractures and corrosion.

Note 1: The difference between PSIG and PSIA is the “measured” pressure is the difference between the unknown pressure and the atmospheric pressure. This difference is referred to as the gauge pressure (PSIG), whereas the true pressure, called absolute pressure (PSIA) includes atmospheric pressure. To obtain operating pressures in PSIA add 14.7 to gauge pressure PSIG.

Note 2: Cast iron and fabricated exhaust heads have different dimensions and therefore different capacity ratings for equivalent connection sizes.

Carbon Steel - Type 40EHMF

Wright Austin custom fabricated carbon steel exhaust heads are used to reduce visible condensate plumes and to recover various chemistries prior to venting to atmosphere.
