Reel Exhaust Extractor

ALAN-U/C-N

23.05.2019

Flow resistances are given for the hose completely wound onto the reel.

Hose of thermal resistance 150ºC (short duration 200ºC).

First hose section (near the nozzle) is of length 2 m and of thermal resistance 300 ºC (short duration 350ºC);
further hose section is of thermal resistance 150ºC (short duration 200ºC).

– car,

– medium size vehicle,

– truck.

To install the reel extractor to the wall or column apply a wall bracket, delivered on demand of Customer.
For technical data of the fans type WPA-

N see the KLIMAWENT S.A. catalogue, in Section “FANS”.

STRUCTURE AND FUNCTION

The Reel Exhaust Extractor consists of a winding reel installed in a framework (adapted for mounting under the
ceiling or on a wall). Onto the reel is wound a hose with a nozzle. Nozzles are adapted to the diameter of the
hoses (and selected to

the Customer’s requirements) and are delivered upon separate order. Specification of the

nozzles is in the KLIMAWENT S.A. catalogue.  The hose is being wound manually to the requested operational
length, whereas hose recoiling onto the reel is proceeding due to the spring mechanism which is located on the
right side of the reel. On the hose is fastened a rubber stopper which limits the hose recoiling while it is completely
wound onto the reel. The nozzle has to be clamped at the exhaust pipe of the serviced vehicle by means of a
clamp gripper.  Additionally, the nozzle is sucking also the ambient air,  mixing it with the exhaust volume and
thus lowering the temperature of the exhaust fumes. The reel is mounted in slide bearings in the side supports of
the framework.  A grease nipple is located on the right wall of the framework.  Whereas, on the left wall of the
frame  is  placed  the  outlet  of  the  extractor,  to  which  can  be  installed  a  built-on  radial  fan  type  FA  (delivery  on
separate order).
The outlet of the extractor (or of the FA-type fan) ought to be connected with a rigid ventilation conduit to discharge
the exhaust volume outside the process room. Section and length of the ventilation conduit (connecting the fan
outlet) should be selected in such a way that the minimum flow at the nozzle is not lower than the value given in
the section 4 “Technical Data” – recommended extraction volume.
Additionally, the Reel Exhaust Extractor can work with a flange type fan type WPA-E-N mounted independently
on  a  wall  bracket  or  with  a  roof  fan  type WPA-D-N.    To  control  the  function  of  the  extraction  fan  is  the  motor
protective switch selected individually according to the rated current of the fan motor. (The motor protective switch
does not belong to the standard delivery).
As a standard, the hose reel is equipped with:

●

band brake

– to slow down the rotations of the reel during recoiling,

●

ratchet gear (locking pawl)

– to block the hose assembly in the needed position.

Reel extractors ALAN-U/C-8-N and ALAN-U/C-12-N provide possibility of recoiling hoses of diamet

ers: Ø100,

Ø125 or Ø150 mm and maximum length of 8 metres and 12 metres. The extractors can be equipped with a shut-
off damper that opens and closes automatically while coiling / recoiling the hose onto the reel.  Therefore, it is
possible to apply a smaller extraction fan,  while the extractors are connected to the main collecting ductwork,
whereby the use coincidence factor is lower than 1.  In each version the free hose overhang,  (in a state when it
is fully recoiled on the reel), should be from 1,5 to 2 meters.
