4. The Bendix inlet regulating valve (IRV) can be installed as an alternative to direct
compressor turbocharging when it is found that turbocharger supply air pressure
exceeds the limits of a particular compressor model. The function of the IRV is to
maintain a pressure of 10 psi or less at the compressor inlet regardless of
turbocharger supply air pressure. While use of the IRV eliminates concern with
turbocharger pressure output, the installation must comply with all other compressor
turbocharging parameters. The IRV, part number 104171, can be installed on all
Bendix compressors with the exception of the BX-2150.
COMPRESSOR TURBOCHARGING PARAMETERS
TuFlo 400, 500, 501 & 1000 Compressors
1. Air entering the compressor inlet during the loaded cycle must not exceed 250F
(121C). A metal inlet line is suggested to help meet this parameter.
2. Compressor crankshaft speed must not exceed 2200 rpm.
3. Air pressure at the compressor inlet must not exceed 25 psi (172 kPa).
4. Turbocharging is not recommended for fully air cooled versions of the TuFlo 500 and
1000 air compressors.
TuFlo 600, 700 & 1400 Compressors
1. Air entering the compressor inlet(s) during the loaded cycle must not exceed 250F
(121C). A metal inlet line is suggested to help meet this parameter.
