Servicing
The only moving parts that require servicing on the
Airflow
range of Dry Filter Spraybooths is the Extraction Fan. The
type of Fan used on these Booths is the patented
Airflow
Cartridge Fan, the features of which are a long working life
and ease of maintenance. Servicing of the Cartridge Fan should only be conducted by a competent mechanical engineer
and limited to the two operations detailed below.
DRIVE BELT REPLACEMENT AND TENSIONING
1. Ensure the power is isolated from the Spraybooth and that a lock is fitted to keep
the isolator in the “Off” position.
2. Unbolt the belt guard from the end of the motor shaft and remove the guard.
3. Visually check the condition of the drive belts, if they are still in a serviceable condition, go straight to Section 6.
4. Loosen the M16 nuts, which are used to tension the motor and its mounting plate until the belts are slack enough to
remove.
5. Fit the new belts onto the pulleys ensuring there are no twists.
6. Re-tension the motor mounting plate using the M16 nuts until it is possible to deflect the belt by 10-15mm as it enters
the fan housing with moderate finger pressure. Caution: Do not cover tighten drive belts as premature wear of motor
bearings, shaft bearings and other drive components will result.
7. Replace belt guard.
8. Test run the Fan.
REMOVAL AND REPLACEMENT OF COMPLETE CARTRIDGE ASSEMBLY
1. Isolate the supply to the Spraybooth and ensure a lock is fitted to maintain the isolator in the “Off” position.
2. Remove the filter medium to gain access to the inside of the Spraybooth.
3. Remove the finger guard.
4. Remove the bolt and washer from the centre of the fan shaft and by means of a suitable extraction puller remover the
fan impeller.
5 Prize away the flinger seal from the fan shaft.
6. From the roof of the Spraybooth, remover the four bolts securing the cartridge arm to the two rolled steel angle
supports of the fan casing. Please Note: Be careful not to lose the shim washers which are trapped between the
cartridge arm and the fan causing as these must be replaced in exactly the same position when re-installing the
cartridge arm.
7. Lift the cartridge vertically upwards approximately 50mm and then withdraw the complete cartridge assembly from
the side of the fan casing.
8. It is now possible to work on the complete cartridge assembly. However, you may now wish to remove the motor
connection wires and take the cartridge to your workshop for overhaul.
