Page 8: Overview
Overview BALLAST INJECTION General Blower Operation The NVE BLOWERS are severe duty vacuum INTAKE EXHAUST pumps, designed to be used in liquid waste pumping systems where extended operation is desired. The pump incorporates a ballast air cooling system to provide superior cooling, allowing for extended operation. -
Page 9: Location Of Serial Number
Specifications Sereial Number Operating Environment The 4307 and 4310 blowers are designed to move atmospheric air. Do not use to move explosive or corrosive gasses or operate the blower in an area with explosive gases. -
Page 10: Performance (Reference Only)
4000 When installing a NVE 4307 blower we recommend a normal R.P.M. range from 2700 to 4000. Other speeds are o.k. as long as exhaust gas temperatures read on the supplied thermometer do not exceed 290 degrees F over ambient temperature. -
Page 11: Dimensions
The noise level of the blower may increase with higher levels of vacuum and RPM. To minimize noise, operate the blower at the minimum speed and vacuum level required to achieve the desired performance results. nvesalesrep.com | 888.814.9191 4307 & 4310 Blower | 11... -

Page 13: Storage
In the event damage has occurred, first file a claim with the carrier and then contact NVE for assistance. Keep all intake, exhaust and ballast ports covered to prevent accidental ingestion of materials into the blower. -

Page 15: Belt Drive
Couplers must be guarded to prevent entanglement. Belt Drive All NVE blower input shafts are equipped with an outboard roller bearing which allows the use of V-belt. The driving pulley from the prime mover must be mounted on the intake side of the blower to prevent unloading of the blower bearings. -

Failure to do so may result in rotor contact with housing. Use only clean piping insuring it is free of dirt, scale, cuttings, weld spat- ter, and foreign materials of any kind. nvesalesrep.com | 888.814.9191 16 | 4307 & 4310 Blower... -
Page 17: Recommended Accessories
Inlet Filter The intake filters are designed to ensure maximum airflow efficiency why keeping out unwanted debris. The filters 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. -
Page 18: Pressure Relief Valve
If the blower is intended to be used in pressure mode then a pressure relief valve is required. NVE recommends the use of Kunkle pressure relief valves as they have been proven to work well and have sufficient flow capacity. -
Page 19: Check Valves
A primary shutoff is to be used with the blower as a first line of defense to prevent liquid from entering the blower. It is critical that an appropriately sized primary shut off is used. Contact NVE for assistance with selecting the shutoff. Secondary Shutoff/Moisture Trap The secondary shutoff or moisture trap should also be appropriately sized for the air flow application. -
Page 20: Starting The Blower
Start the blower and check the appropriate parameters as listed in the mainte- nance schedule under the Maintenance section. Stopping the Blower When stopping the blower, if possible, remove all vacuum and pressure from the blower. 20 | 4307 & 4310 Blower nvesalesrep.com | 888.814.9191... -
Page 21: Cold Weather Operation
Use the recommended oil for the operating temperatures. If temperatures are so cold that the blower cannot warm up, enclose the blower allowing for sufficient clearance from parts to prevent contact with hot or moving components. nvesalesrep.com | 888.814.9191 4307 & 4310 Blower | 21... -

It is therefore up to the operator to adjust the following schedule accordingly. Lubrication: Unlike a typical rotary vane vacuum pump, the Challenger Series 4307 high vacuum blower does not use oil in it’s operation. Therefore it is important to periodically lubricate the internal parts in the blower to keep it free of rust and corrosion, which can cause seizing or catastrophic failure. - Page 26 • Tighten the four fasteners in an alternate manner to maintain even pressure on the spring during compression. • Work the valve handle back and forth several times to ensure free movement. 26 | 4307 & 4310 Blower nvesalesrep.com | 888.814.9191...
