Fairchild
M85D
FAIRCHILD - Relays
Features
• The basic mathematical expression for the Fairchild Model 85D is PO = PS + K where PO is output pressure, PS is signal pressure and K is the spring constant
• Two stage pilot operation allows precise control of set points
• 14 SCFM flow capacity in a small size unit allows use in applications requiring high flow and/or fast response
• Low air consumption preserves air and other costly gases
• Compact size permits installation where space is limited
• Available in 1/8", 1/4" and 3/8" standard port sizes - versatility makes it easy to design into new and existing applications
