Introduction
General Information
About National Vacuum Equipment
Congratulations! You now own a quality vacuum/pressure pump proudly
manufactured in the U.S.A. by National Vacuum Equipment, Inc. You
have not only acquired a superior piece of equipment from a qualied
dealer, you have hired a team of vacuum experts. We stand ready to
work with your dealer to answer your questions and provide you with the
information necessary to keep your equipment in peak working condition.
Thank you for putting your trust in National Vacuum Equipment.
Our Mission
We are dedicated to the production and wholesale distribution of quality
vacuum system products at a reasonable price, on a timely basis.
We are a “one-stop shop” for manufacturers and distributors of vacuum
equipment.
Our History
National Vacuum Equipment, Inc. was founded in 1980 by Bruce Luoma.
The Company started as a retailer of vacuum pumps. Soon after it
started, the Company secured the rights to exclusive distribution of the
Battioni vacuum pumps in North America. This helped the Company to
evolve into its current status as a wholesale supplier.
To reach the goal of becoming a full service supplier of vacuum system
components, the Company began fabrication of its own line of
components, purchased and developed its own line of vacuum pumps,
and began purchasing for resale, various valves and accessories.
Today, NVE has full service machine, fabrication and powder-coating
shops complete with CNC-controlled production equipment designed for
close tolerance work. The company has a highly trained staff, all of whom
are dedicated to quality.

Overview
General Blower Operation
The NVE BLOWERS are severe duty vacuum
pumps, designed to be used in liquid waste
pumping systems where extended operaon
is desired. The pump incorporates a ballast
air cooling system to provide superior cooling,
allowing for extended operaon.
The air enters the intake under vacuum or at
atmospheric pressure. As the rotors rotate, a xed volume of air is moved along
the wall of the cylinder towards the exhaust where the pressure and temperature
of the volume of air increases. If the intake air is below atmospheric pressure,
cooling air will be drawn in when the rotor p passes the ballast port.
The airow capacity of the machine (in ACFM) is nearly proporonal to the speed
of the machine and is nearly constant with changes in inlet or outlet pressures.

Sereial Number
Location of Serial Number
Each blower should have a brass colored tag with an embossed serial number. In
addion, the serial number and blower direcon as assembled at the factory are
stamped into the top of the housing as shown:
Specifications
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. Any materials in the intake
air must be ltered and separated from the air by means of an intake lter, mois-
ture trap and/or a cyclonic lter.
The ballast inlet must be posioned and protected from ingesng debris, uid or
explosive gases.
Operating Limits
The blower must be operated within all limits at all mes. This typically means
the blower performance is limited by the exhaust temperature and temperature
rise over ambient for the blower.
*Exhaust temp and temp rise limited, †Pressure rise is from inlet to outlet, ‡Temperature rise is
exhaust minus ambient temperature surrounding blower (note if enclosed)

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.

The maximum allowable operating
vacuum will vary depending on R.P.M.,
ambient temperature, altitude and
time running. The basic principle to
keep in mind is - faster R.P.M., higher
air temperature and longer run time all
equal more heat in the pump. When
installing an NVE 4310 blower we
recommend a normal R.P.M. of 4000.
Other speeds are o.k. as long as exhaust
gas temperatures read on the supplied
thermometer do not exceed 375
degrees F.
