4307 & 4310 Blower | 17
The intake and exhaust system can be plumbed with 4” or 6” hose. Four inch hose
will provide a more compact system while the 6” hose will maximize the eciency of
the system.
The ballast system should be plumbed using 4” hose minimum. Be sure to locate the
ballast inlet away from heat, debris and uid sources as exposure to these may result
in damage to the blower.
Recommended Accessories
Exhaust Silencer
Posive displacement blowers are inherently noisy due to their design. NVE oers
compable silencers for the exhaust to reduce decibel levels in the operang environ-
ment.
If using a non-OEM silencer, it should be tested for eecveness by blanking o the
inlet and monitoring exhaust gas temperature with the blower running for at least
one hour. The blower should not exceed specied exhaust gas temperatures.
Tunable Ballast Silencer (4310 Blower)
A tunable ballast silencer provides for eld tuning of the ballast circuit to minimize the
noise for customer specic operang points.
If using a non-OEM silencer, it should be tested for eecveness in the same fashion
as described above for exhaust silencers.
Inlet Filter
The intake lters are designed to ensure maximum airow eciency why keeping out
unwanted debris. The lters supplied by NVE use a stainless steel screen and can be
cleaned.
Four Way Valve and Hoses
If it is intended to operate the blower in the pressure mode, a four way valve will be
required. The 4-way valve size should match the hose size used in the applicaon.
