Define your term "surge vessel" and "accumulator".
Specifically, what is your duty cycle of air required, compressor "on" pressure and "off" pressure, and air allowable pressure range at the service header.
Also, how big an accumulator vs how big a storage tank are you considering.
A large pressure tank with a large connection pipe to the supply header may suffice by itself.
I am assuming your required product is medium pressure air, not hydraulic fluid.
