1PRESENTATION
1.1 Foreword
Thank you for choosing a R4000 mobile air decontamination unit developed and manufactured in
France by CALISTAIR.
This technical manual must be read, understood and applied to ensure that the appliance functions correctly.
Air treatment technology by non-thermal catalysis is based on a patented procedure which destroys most
chemical and microbiological pollutants in the air.
The R4000 unit is a very powerful air treatment system. It can treat up to 4,000 m3/h.
The core technology is protected by two filter levels (G4 + F8). After decontamination, the air is finally
filtered by a H14 (or even H15) high-efficiency filter at the outlet for absolute particulate filtration in order
to achieve the highest expected air class levels.
It is equipped with a latest-generation PLC enabling it to manage all the programmed functions via the
various built-in sensors.
Its automatic regulation system enables it to maintain the desired air flow however clogged its filters are or
to adapt its ventilation airflow to the concentration of pollutants present.
This system is designed to function completely independently in the presence of people. It does not generate
any additional pollutant in the environment of the room treated, subject to compliance with the usage
conditions.
It can be connected to a ventilation duct network and controlled by an existing or not yet existing fixed air
handling system (heating / air conditioning).

1.3 Principle
Figure 1: diagram of the R4000 and treatment modules
•The air to be treated is captured via the bottom of the machine and drawn into the R4000 unit by
the fan (motorised impeller).
•The particles are trapped by the particulate filters at the unit inlet (G4 course filtration + F8 fine
filtration).
•Chemical and microbiological pollutants are almost entirely destroyed by the non-thermal catalytic
reactor.
•The adsorption and high-efficiency filters (H14 or U15) then complete the treatment.
1.4 Technical description
1.4.1 Design
The casing of the unit is composed of a galvanised steel double wall, with rock wool thermal and
acoustic insulation (double skin). The inner and outer walls are smooth, avoiding the formation of biofilms
(NF S90-351 standard). The gaskets and packings are class L2, satisfying the EN1886 standard for improved
sealing. The G4 and F8 filters and the brackets for the bulbs and catalysts are mounted on rails. The
adsorbent and high-efficiency filters are clamped on a seal surface via cams (no need for tightening tools).
The inside of the unit is accessed via a seal-mounted door locked with a square recess key at two points for
improved sealing.
1.4.2 Filtration
The R4000 is equipped with several filtration levels as standard:
•G4 gravimetric filter according to the EN 779 standard. Fully recyclable pleated polypropylene media
which can be incinerated,

User guide
R4000 MOBILE AIR HANDLING UNIT
Version: 2.4

Page 4 / 21
•F8 opacimetric filter according to the EN 779 standard with compact cells. Fully recyclable glass-fibre
media which can be incinerated,
•Adsorbent filter: standard or specific depending on the sector of activity,
•High-efficiency (H14) or ultra high efficiency (U15) absolute filter according to the standard EN 1882.
1.4.3 Treatment by the non-thermal catalytic process
The patented non-thermal catalytic reactor of the R4000 is composed of an alternating arrangement
of 3 stages of catalyst deposited on a support and two frames, each fitted with 4 UV-C bulbs mounted in a
flat configuration. The bulb frames are electrically connected to the electrical cabinet located at the rear of
the appliance. A PLC manages all the functions of the R4000 with the assistance of pressure, temperature
and humidity sensors. Additional sensors, in particular for specific chemical pollutants, can be incorporated
into the R4000 for particular needs.
1.4.4 PLC
The R4000 unit is equipped with a latest-generation SAIA PLC (PCD3.M90 type). It enables the air
handling unit to operate independently, maintaining a constant flow however clogged the filters are. It
manages all the sensors on the machine, provides traceability of all operations and warns in case of
malfunction or if maintenance operations are necessary. The data can be exported via an Ethernet cable. If
the appliance is connected to the network, the information can be recovered and the PLC updates performed
remotely.
The PLC is integrated into an electrical cabinet at the rear of the scrubber. A colour touchscreen on the front
displays all the operations and allows the user to configure the machine settings.
1.4.5 List of sensors and probes
The R4000 is equipped with sensors and probes as standard. Their type and number may vary
depending on the environments and issues to be treated.
•Temperature and Hygrometry probe (air inlet)
•Pressure sensor to measure the air flow
•Differential pressure probe (G4 + F8)
•Differential pressure probe (adsorbent + H14 or U15)
The control screen displays the flow (in m3/h), the temperature (in °C), the relative humidity (in %), the
consumption of the two levels of UV-C bulbs and the motorised impeller (in W) in real time.

Figure 2: R4000 electrical compartment and PLC
1.4.6 Fan
The R4000 uses an electronic motorised impeller (EC motor) satisfying the fan electricity
consumption reduction standards (Erp 2015 directive). It allows a very precise, quiet regulation from 0-10V,
maintaining a constant flow and adapted timing according to the issues to be treated and the environment.
For example, the available pressure is 950 Pa at 3,000 m3/h.
1.4.7 Connection to a ventilation network
The R4000 is a mobile, autonomous air handling unit. In some cases (e.g. location in a class 4
hazardous zone, centralised treatment of several rooms, etc.), it can be connected to a ventilation system
using an optional painted galvanised steel connection mounted on the unit by tightening on a seal. It can
thus be connected to ducts of diameters ranging from 150 (DN150) to 400 mm (DN400). Other connection
components are available (consult us):
•Fixed connection kit,
•Fixed suspended filter ceiling with unidirectional flow equipped with terminal filters for zone 4,
•Removable filter ceiling with unidirectional flow equipped with terminal filters for zone 4,
•Flow diffuser box for zone 3,
•Negative pressure kit,
•Mobile kit for overpressurisation with isolation panel for the fresh air intake,
•Air-mixing plenum (return air / fresh air) incorporating air heating and cooling batteries.
1.4.8 Castors
The appliance is equipped with four swivelling castors to facilitate movement. The two front castors are fitted
with a brake. Their tread is specific to clean room use and is resistant to chemical products.

because heat rises naturally. As the R4000 is in vertical position, the temperature probe on the supply
(located in the top of the machine at a height of 1.9 m, shown on the right on the screen) therefore naturally
displays a higher temperature than the temperature probe located at the return (at the bottom of the
machine at a height of 0.2 m, shown on the left on the screen). This temperature difference creates a light
flow of ascending air which sometimes results in slight differences in pressure loss in the filters.
2.2.1.2 Settings configuration
•Click on the “Tools” icon to configure the settings for the air treatment flows during the day
and night “impeller flow setpoint day” and “night ”on the machine and programme the time slots
“ Day/night time slot management ”.

•The “Physical Configuration” is factory-set according to your usage (mobile, fixed, temperature and
pressure cascades, optional additional sensors and probes, etc.). You can only access this level and
alter the settings if you are logged in as administrator (“ADMIN”).
2.2.1.3 Traceability
•To go to the R4000 traceability screen (graphs showing performance over time) directly, click on the
icon then on the criterion you want to view.
Figure 10: standards traceability criteria
•Traceability criteria are indicated in Figure 10. These are basic criteria to be found on all mobile
R4000 units. The measurements of the temperature and humidity made at the inlet (also called
“return”) and at the outlet (also called “supply”) of the air, consumed power of the fan (motorised
impeller) and the UV bulb stages (stages 1 and 2) the pressure and air flow of the fan and the
pressure losses of the various filters can thus be monitored. Other criteria can be added and the
related sensors can be managed by the PLC such as temperature and humidity on the supply air,
the air quality monitoring sensors (CO2, VOC, specific gas), differential pressure probes in the rooms,
a sensor measuring the particulate concentration for monitoring ISO class, etc.
•To view how these criteria develop over time, simply click on one of the criteria. E.g. by clicking on
“ Motorised impeller pressure and flow rate” , it is possible to monitor the flow rate graph for the air
treated by the R4000 and thus see when the machine stopped working for example. It is then
possible to zoom in or out on a desired period, move around the time scale, save the log, etc.

N.B. The procedure for extracting data from the PLC (in order to plot the curves in an Excel spreadsheet for
a report for example) is described below in paragraph 2.3.
2.2.1.4 Alarms
•When alarms are triggered, the icon flashes alternately red and green. Click on it to access the
alarms log. In the example below (Figure 12), we have simulated the failure of the energy meter for
a bulb stage. The log displays an alarm on the UV bulbs of level 2 (fault no.9) and instantly
determines that the failure is linked to the energy meter (fault no.18). Following this, we stopped
the R4000 to simulate a repair and the “machine stopped fault” appeared (fault no.19).

3MAINTENANCE
Some components of the R4000 must be replaced to ensure optimum efficiency. These include the
G4 and F8 filters, the catalyst, the UV-C bulbs, the adsorbent filter and the H14 (or U15) terminal filter. The
life time of these consumables is listed in Table 3 and Table 4 in paragraph 3.4.
CALISTAIR undertakes to regularly replace all these components and the other components (in case of
failure) under a maintenance contract.
Please contact us directly for further information.
Before any operation it is essential to switch off the appliance (see procedure on paragraph 2.2.1.5).
3.1 Changing the bulbs
As the UV bulbs have a high power, their surface can be hot. It is essential to allow them to cool
down before cleaning them.
•Open the unit access door,
•The two UV-C bulb frames are visible. Simple remove the bulb frame connectors,
•Remove the UV bulb frames and replace them with new ones,
•It is essential to clean the bulbs before they are installed in the unit. To do so, use a soft cloth
soaked in alcohol (e.g. ethanol, isopropanol),
•Clean the entire surface of the bulbs, ensuring there are no marks remaining,
•Place the new bulb frames in the appliance.
• Never clean the catalyst,
• Never use abrasive cleaning products,
• Avoid touching the bulbs with your hands. The grease left interferes with the proper transmission of
the UV light and reduces the life time of the bulbs.
Unbroken used bulbs are recycled. You can choose to send them to your dealer who will send them
to the recycling channel or to take them to the bins available in many collection points (supermarkets, DIY
stores, etc.). Broken bulbs cannot be recycled and must be disposed of in the dustbin.

User guide
R4000 MOBILE AIR HANDLING UNIT
Version: 2.4
Update: 06/2019
Page 18 / 21
3.2 Changing the particulate filters
The efficiency of the appliance depends on the condition of the particulate filters. The more clogged
the filters are (and therefore the more the pressure losses increase), the more the fan has to compensate
for these pressure losses by increasing its power. The electricity consumption thus increases and if nothing
is done, the air flow will finally decrease and there is a risk of the motorised impeller breaking down.
The average frequency for changing the particulate filters is three to six months for the G4 filter, six
to twelve months for the F8 filter, 18 months for the adsorbent filter and 36 months for the H14 absolute
filter. It depends on the amount of dust and pollution in your environment and the frequency of use of the
appliance. The PLC manages warnings in case of clogging of one or more filters.
•Open the R4000 access door after shutting down the appliance (shutdown procedure paragraph
2.2.1.5),
•Remove the used G4 and F8 filters,
•Replace them with new filters in the spaces provided for this purpose in the following filtration order:
G4 first then F8 second. Warning: observe the airflow direction indicated on the F8 filters,
•Change the adsorbent filter by opening the cams on each side. Remove it and replace it with a new
one (supplied by CALISTAIR). Close the cams on each side,
•Change the absolute filter by operating the cams. Slide the used filter in its drawer. Replace it with
a new one (supplied by CALISTAIR). Slide it upwards until it is against the seal and operate the cams
to guarantee that the filter is completely sealed.
Used particulate filters cannot be recycled due to the impurities they contain. To determine the type
of this waste (non-hazardous, infectious, etc.), consult your Health, Safety and the Environment manager.
3.3 Changing the catalysts
The average life time of a catalyst is three years.
•Open the R4000 access door after shutting down the appliance (shutdown procedure paragraph
2.2.1.5).
•Remove the used catalyst frames.
•Replace them with new catalysts (supplied by CALISTAIR).
Do not touch the catalyst. The used catalyst is non-toxic. Therefore there are no other particular
precautions to be taken. Treat the catalyst and its frame as standard metal waste.
