FORMULA AIR “CARWASH PACKAGE”
EXTRACTION SYSTEM
Especially conceived for the vacuum cleaner section
The goal :
Breach the carwash sector with a complete package, easy to install with everything the client needs.
The client installs the ducting, places the filter unit (with a cyclone before it if recommended) and connects the
power and compressed air. The control unit in the filter is preconfigured at our factory.
The story :
With an outstanding and long term experience in the carwash vacuum cleaner section, Formula Air The
Netherlands has been working on simplifying the approach to this growing sector with a very competitive and
innovative solution : a “plug & play” package for up to 10 suction points.
The advantages :
- The filter unit is quickly placed and connected (“plug & play”)
- The client receives all the components he needs to make a complete installation.
- The service is quick and easy
- The replacement is easily achieved
- One filter model for all purposes (up to 10 suction points)
- It can be modular. The client can have 6 suction points today and go up to 10 points at a later date by just
adding ducting.
The downsides :
- It cannot have more than 10 suction points. So if a client wants 12 suction points, he needs to take two units
which might become expensive compared to a conventional system.

The composition :
- A CHFU unit reviewed and preconfigured at our factory with :
o A specific Elmo Rietschle pump 2BH1930 (replacing the original one),
o A specific frequency regulator (replacing the existing one),
o A complete electrical control unit that suits the needs of this type of installation,
o A sensor built in the loaded air side of the unit coupled to the control unit that measures the need for
more or less power,
o Compressed air tank controlled by a timer pulse valve TEC-33 to clean the cartridge,
o Side inspection doors for an easy cleaning and cartridge replacement.
- Ducting elements including :
o Piping going from Ø50 to Ø152,
o Bends and branches,
o Pipe couplings,
o 2 pneumatic sliding dampers in Ø50.
- Cleaning components including
o Flexible hoses,
o Plastic slit nozzles,
o Rotary hose connectors.
- Optional : a cyclone to pre-separate the heavier particles

The details (how it works) :
The installing of the vacuum installation goes very quickly as the client just needs to place the filter where it is most
convenient, connect it to the power grid and compressed air and install the ducting elements with the two
pneumatic dampers at the end of the lines (these have to be connect to an electrical source and compressed air as
well) and the installation is ready to go!!
To start the unit, the power switch must be in the “on” position and a user needs to press a “start” button which
activates the vacuum cleaner for a defined amount of time (in minutes). When the unit is started it brings the
frequency regulator up to 30 Hz (idle state).
At 30 Hz, the pump treats a volume of 300m³/h and although one suction point only needs 150 m³/h, it doesn’t go
lower in order to have a good base functioning. To compensate, a safety valve within the unit opens up when too
much under-pressure is reached with just one suction point open.
When all suction points are opened, or when the cleaning cycle is engaged, it runs up to 70 Hz in order to create
enough vacuum to reach 1500m³/h. This insures a constant airflow of +/- 25m/s at all times in the ducting.
All the suction points in the installation are equipped with an “ON” button that
the user can activate. These are connected in line so that only one user needs to
push the button to start the installation. It automatically auto-regulates itself
depending on the amount of users (depending on the amount of open nozzles).
The duration of the vacuum is predefined in the control unit at the factory. Once
the time is up, the installation shuts down and the user has to push the “ON”
button again to keep using the suction point.
The suction at any one point starts when the slit nozzle is removed from its holder.
The slit nozzle takes air in which creates a pressure drop inside the filter and the
under-pressure sensor sends a signal to the control unit to give more power to the
pump. The unit measures and increases the pump activity as new suction points
are put to use. It runs back down as slit nozzles are placed back into their holders. These nozzles are held
in place by the vacuum created inside the closed holder. The pump will continue until the timer runs out
and the excess under-pressure will be absorbed by the safety valves integrated in the unit.
The filter cartridge is cleaned by a compressed air burst from the integrated airtank (in the upper part of
the filter). The frequency and length of the burst is defined by the TEC-33 timer control integrated on the
valve of the airtank. The user can easily monitor the differential pressure between the clean and loaded
air side of the unit indicated on the differential pressure manometer. As a standard it is set to clean every
5 minutes and only when the pump is running.
The cleaning cycle of the ducting is very important. It can be programmed at regular intervals in the
control unit but it can also be launched manually by pressing the “cleaning” button on the unit. The unit
goes up to 70 Hz for a defined length of time to create the maximum momentum possible before the two
pneumatic sliding dampers at the end of each line open up for a few seconds to create a huge airflow
which will empty out the ducting towards the filter.
Once the unit is at a full stop, the dustbin at the underside of the filter can be removed to be cleaned.
The monitoring of the filter cartridge is very important for a good filtration. Replacing a damaged
cartridge on time is crucial and for this reason, the unit is equipped with two inspection doors on the front
of the unit. The smaller of the two (on top) gives access to the clean air side of the unit where the bolts of
the cartridge are loosened. The bigger inspection door in the loaded air side is designed to remove the
cartridge in an efficient manner.

Overview of the unit :
Differential pressure display :
Shows the differential pressure inside the filter between the clean and loaded air sides.
Under-pressure detector :
Is place on the loaded air side of the unit and measures the need for under-pressure. It sends a signal to
the control unit which activates the frequency regulator.
Control unit (6VO) :
The control unit reacts to the need of power from the suction points which is defined by the under-
pressure detector in the filter. This is the “brain” of the installation as it controls the time the installation
starts, the time at which it shuts down, the cleaning cycles, the speed of the pump. It activates the pump
when the user pushes on the “start” switch.
Frequency regulator (4VO) :
This controls the speed of the pump. It goes from 30 Hz up to 70 Hz depending on the amount of suction
points in use at one time. It is controlled by the Control unit.
Control panel :
These are the main switches that activate the unit? There are also two lights that show the status of the
unit.

The control panel :
MAIN POWER : This puts the unit under voltage. It does not activate the pump or control unit.
CLEANING : This sends a signal to the control unit to start up the cleaning cycle. Once started, it cannot be stopped.
TEST : This launches the filter unit to start the process as if one of the suction points was being used. It is the same as
the “ON” button at each cleaning station.
ON/OFF : This starts up the main power of the different elements
“WORKING” : This is a green lights that is on when the unit is turned on and is powered up ready to be used, or in
use.
“MALFUNCTION” : This is a red lights that turns on when there is a malfunction in the unit. Usually linked to a
control unit problem or an obstruction of sorts.
