1.1. EQUIPMENT PURPOSE
69000-00-0042 R3
1.1. Equipment Purpose
1.1.1. General Description
The GrainVac VR12 is a high capacity air fan that creates a vacuum for picking up and
moving grain. The GrainVac VR12 is designed and manufactured to move grain from
grain storage facilities into grain transport vehicles.
1.2. Intended Use
This equipment is designed solely for use in customary agricultural or similar operations.
Use in any other way is considered as contrary to the intended use. Compliance with
and strict adherence to the conditions of operation and maintenance as specified by the
manufacturer, also constitute essential elements of the intended use.
This equipment should be operated, maintained, serviced, and repaired only by persons
who are familiar with its particular characteristics and who are acquainted with the
relevant safety procedures.
Accident prevention regulations and all other generally recognized regulations on safety
and occupational medicine must be observed at all times.
Any modifications carried out to this equipment may relieve the manufacturer of liability
for any resulting damage or injury.
1.2.1. Misuse
Running material such as sand, dirt, fertilizer, water, rocks, etc. is considered misuse,
will cause severe damage to the GrainVac, and will void the warranty.

1. INTRODUCTION REM - GRAINVAC VR12
1.3. COMPONENTS OVERVIEW
89000-00-0042 R3
1.3.1. Functional Overview
The GrainVac is a simple and reliable system. It uses a vacuum to produce a flow of air
that conveys grain or material to the body of the machine. The flow of grain is directed
into an auger that conveys it to the transport vehicle. The heart of the system is the
rotor(s) (also known as blower(s) or fan(s)). The rotor(s) (A) remove air from the body
and places the entire system under vacuum. This vacuum causes air and grain to enter
through the intake (D) and flow through the hose (C), into the body (E) of the machine.
When the stream of air and grain reaches the body (E) of the GrainVac, it is separated
by the drum (B).
The stream of material is directed into the auger flighting, moved up the auger tube (F)
and discharged out the end dump double doors (G). The stream of air is cleaned of large
particles by the rotating drum and the air continues on through the drum into the rotor(s)
(A). The rotor(s) force the air out of the body into the exhaust (I) and out the air outlet
(H).
