1 General Information
1.1 Preliminary Information
The air stream fan simulates the air stream that is normally produced during driving simulation of
motor vehicles during performance tests on roller dynamometers.
The air cooling fan blows cool air via a low-lying, large exhaust passage on the engine cooler and
under the vehicle. The engine temperature of the tested vehicles is thus maintained at normal
operational temperature. The heat accumulation underneath the vehicle is blown off, avoiding
damage to the corrosion protection of the automobile body and overheating of the the drive unit
and tires.
1.2 Safety Instructions
Read the standard operating procedures and user’s manual carefully before operating
the cooling air fan! MAHA will not accept any claims for damage or service costs occurred
due to non-compliance with these operating instructions.
The accident prevention rules and regulations of the Professional Association, the Workplace
Directive and the Reich Garage Directive, as well as the latest relevant VDE (Association of
German Engineers) regulations shall apply to the operation of the air cooling fan.
The official accident prevention regulations must be complied with at all times.
All work done on electrical parts of the equipment is to be carried out by trained, qualified
electricians or service technicians only. Before any kind of service or repair work is done,
disconnect the cooling air fan from all power supply and turn off the main switch, if
necessary!
The air cooling fan should be operated by trained personnel only!
Protect all parts of the installation from humidity and moisture!
The air cooling fan is only to be used for its intended purpose as described in the operating
instructions (Simulating the airstream which occurs during normal driving conditions while
conducting performance tests on roller dynamometers)!
Make sure that the cooling fan is properly and firmly positioned before starting operation!
Do not deposit any parts (tools, vehicle parts etc.) on the cooling fan!
Never insert any objects into the guard grilles of the cooling fan!
The noise emission value created when the air cooling fan is in operation is more than 70 dB
(A) in the work area of the operational personnel. Ear protection should be worn. The
protection should be approved for noise levels of up to 120 dB(A).

2 Installation and Operations
2.1 Installation
2.1.1 Air Stream Fan AIR 1 and AIR 2
Air stream fan AIR 1
A: Air exhaust
B: Handle to swing around the fan
C: Lever to lock the fan
D: Power-supply plug
The air stream fan AIR 1 is equipped with a power-supply plug (D)for 230 V mains supply. The
ON/OFF switch is situated on the back side of the fan.
The air stream fan AIR 2 must be connected to 400 V three-phase mains. The air stream fan is
equipped with 4 rollers and can therefore easily be moved to the intended point of use. To ensure
a stable position during operation, two of the rollers are equipped with a locking brake. Normally,
a cable remote control is used to switch on and off the cooling fan. If, however, a MAHA
dynamometer is used, the air stream fan can be operated with the dynamometer's remote control.

2.1.2 Air Stream Fan AIR 5 and AIR 7
Air stream fan AIR 5 and 7
A: Electro box
B: ON/OFF switch, rotary switch
(depending on model and equipment)
C: Connection to LPS
D: Power-supply plug for 400V three-
phase mains
E: Cable holder
F: Air entry
G: Lashings for the air flow scoop
H: Three-phase motor
I: Locking brake for guidance rollers
J: Air exhaust
The air stream fan AIR 5 is available in two different versions. The AIR 5 blows with a constant air
speed and is turned on and off via the dynamometer's remote control. The AIR 5/5 offers a
infinitely variable air flow adjustment which can be regulated manually via a rotary switch situated
on the cooling fan or automatically via the roller RPM of the dynamometer.
