LONG-LIFE SERVICE

Although WALINGA blowers are sturdy, precision-engineered machines, there are several relatively
simple but basic installation and maintenance procedures that must be observed to assure optimum
performance.

It is the purpose of this manual to help you properly install, maintain and service your WALINGA blower;
follow the instructions carefully and you will be rewarded with long-life service.

LONG LIFE DESIGN

WALINGA Rotary Positive Displacement Blowers are designed to give the user the most compact unit
possible. The drive shaft is extended for direct coupling or to accommodate a multiple V-belt drive.

The following standard blowers are available from Walinga:

WALINGA 510 & 614

These high performance blowers offer 700 to 1800 CFM at pressures up to 12 psi continuously.
Gears and bearings are splash lubricated.

Walinga Chrome Blowers

Right-Hand-Drive Option

The standard shaft position on Walinga Super Chrome Blowers is at the left-hand side when viewed from
the drive end. A right hand drive conversion is available to suit specific applications. Walinga or a trained
dealer must be consulted prior to installation or perform this conversion to ensure that the warranty
coverage is not voided. Note that direction of air-flow through the blower will be the reverse of a standard

blower.

SPECIAL FEATURES OF WALINGA BLOWERS

OPERATION

Refer to Figure 1. Rotary positive displacement design
incorporates the use of two figure eight impellers which
rotate in opposite directions to deliver a metered volume
of air. The impellers are separated by minute clearances
which are designed into the unit. These clearances are
maintained by timing gears.

CONSTRUCTION

Walinga blowers are ruggedly built for long life. Impellers
are dynamically balanced to operate without vibration.
Large alloy steel shafts are ground and polished.
Bearings are heavy duty anti-friction type which enable
the blower to maintain its original factory clearances.
Bearings are protected from dirt and contamination by oil
seals. Precision, steel, helical gears are oil lubricated by
a completely self-contained splash system which
atomizes the oil. Breathers are provided to prevent the
air from being contaminated by the blower lubricant.

TYPES OF DRIVE

Direct: Locked bearings on both impeller shafts enable

the blowers to be direct connected. The entire line is
also available with flange adaptors and couplings for
direct connection to internal combustion engines as used
on WALINGA Trailers and Transfer Units. (See Figure

2). In addition, WALINGA blowers are available as
power take off (PTO) units with gear heads in a selection
of ratios to approximately 2.25:1.

V-belt: Walinga blowers can be V-belt driven to permit
changes of speed to accommodate variations in
operation requirements. (See Figure 3)

exclusive WALINGA TIMING HUB which enables the user to
easily retime the unit in the field and has great shock absorbing
qualities (Figure 6).

LUBRICATION

Anti-friction bearings and precision, steel helical gears are oil lubricated by a completely self-contained splash
system which atomizes the oil. No external oil feed systems or coolers are required.

Units are shipped with oil in the gear case or bearing housing. Do not operate before checking lubrication. The
vent and oil level plug arrangement are shown in figure 8. Remove the oil fill plug from the fill hole at the top of the
cover and the plug from the oil level hole located at the side of the headplate. Fill the housings until oil drips out of
the oil level hole. Do not overfill. * Replace both plugs. Use Walinga Super Duty Blower Oil (Walinga Part# 98-
13813-5) In most cases, operating temperature of the blower will be in the 100-250 Deg. F. range. Normally the
gear case should be drained, flushed, and refilled every 100 hours or annually. If inspection indicated it is
necessary, do at shorter intervals. The oil level should be checked daily.

Fig.8 Blower Schematics

* On units equipped with sight glass, check to be sure that oil levels registers a quarter of the sight glass.

OIL CAPACITY LITERS (US QUARTS)

SPECIAL NOTE: As a result of blower operating temperatures, condensation can occur and result in water formation

in the lubricating oil reservoir. It is important that any water accumulation be eliminated, in order to ensure proper
lubrication and long life.

Allow blower to cool down before driving away to prevent condensation and freeze up in cold weather.
