6 Manometers A differential pressure gauge is placed across the filter or fan section to monitor the differential pressure. This is a simple and quick way to get an overview when you are at the air handling unit. We have three versions: Magnehelic manometer, inclined manometer and u-tube manometer. The magnehelic manometer is the most precise.

7 Magnehelic manometer (Item number ) The magnehelic manometer provides a quick and precise Installed on Geniox measurement of the difference in pressure. The differential pressure gauge is used for measurement above filters and fans. It indicates a differential pressure with an accuracy of 1% and can be applied in various ranges of measurement. The magnehelic manometer has a frictionless detection system which quickly indicates the differential pressure. The manometer is designed to withstand impacts, vibrations and significant gauge pressure. The range of measurement is Pa. Operating temperature -6 to +60 C. IP 67. Inclined manometer (Item number ) A simple, visual tool that is easy to read. It will often be necessary to have a filter alarm and visual presentation of the differential pressure by the filters. The manometer measures in Pa and is designed in plastic. Silicone hoses are included. The weight is 560 g. Liquid for filling is included. The range of measurement is Pa. Operating temperature -20 to +60 C. IP 54. Installed on Geniox U-tube manometer (Item number ) This u-tube manometer is also used to measure differential pressure. This is a simple and visual tool. It may be low-tech, but it works and is very reliable. The u-tube manometer is designed as a polycarbonate tube placed in a round aluminium container with sealed bottom. There are two holes in the back for fastening. The scale is in brushed aluminium with blue numbers and divisional lines. The range of measurement is Pa. Installed on Geniox systemair 7

8 Filter guards To maintain a good air quality and to avoid pressure drops, it is essential that you change the filters in time. You can choose a filter guard to monitor the filters, if you choose an air handling unit without control system. Filter guard (Item number ) A simple, mechanical pressure guard. It is easy to set and issues an error signal, if the pressure exceeds the set level. The signal is on/off without any graphs. It is not ideal for VAV operation, as the setting does not allow for variable air volume. 8 systemair

9 Volumeters The volumeter provides you with a quick and simple measurement of the air flow. It is placed over the fan section and is available in a mechanical or digital version. Volumeter (Item number ) Display for measurement of air flow. It provides you with quick and precise information about the airflow. Installed on Geniox Digital volumeter (Item number ) The DPT-Flow pressure transmitter can either provide a pressure or an air volume read out from the fan. The K-value of the fan, has to be setup in the DPT-Flow, for an air flow read out. Pressure, air flow read out scale and measuring units can be adjusted. DPT-Flow is also equipped with terminals for an analogue air flow or pressure output signal. The DPT-Flow pressure transmitter is mounted on the inspection side of the fan section. Supply voltage: 24V AC. Output signal: 0-10 V DC or 4-20 ma. IP 54. systemair 9

11 Stainless steel base and droplet eliminator Stainless steel base The stainless steel base is applied to protect the bottom at the filters and dampers. You should select this, if there is a risk that the aluzinc standard bottom plate corrodes. The base is separated from other metals with polycarbonate to protect against galvanic corrosion. Stainless steel base (filter only) Stainless steel base (filter + damper) Droplet eliminator If there are droplets in the airflow, SystemairCAD will automatically select a droplet eliminator by the humidifier. However, in some cases, it is relevant to select or deselect it. The margin for automatic selection is only one degree, so in some cases it is relevant to consider. It can also be chosen by the run around coil heat exchanger, cooling coil, change-over coil and integrated reversible heat pump. systemair 11

12 Water trap The water trap ensures that condensation is also drained, if a negative/positive pressure arises. The water trap is used for the drip trays in the air handling unit, for example for plate heat exchangers, run-around coil heat exchangers and cooling coils. Water trap (Item number ) It is important to use a water trap for drainage from the air handling unit. The ball inside the water trap ensures that there is no evaporation, if there is no condensation. If the water trap is fitted on the negative pressure side, it protects against any leakage to the outside. The water trap is designed in white PP/ABS plastic. The connection is ø 40 mm, and the ball is included. The height, H, depends on the pressure loss. It is essential that the closing height is correct for the best function. You can read more in the Geniox user manual Draining condensate water. 170 H systemair

13 Inspection window and light With an inspection window and light you can monitor the air handling unit during operation. Light is essential to the safety in large air handling units where you need to go inside the sections. Inspection window (Item number ) The inspection window has been designed specifically for Systemair. It gives you the possibility to inspect a large area. In combination with light inside the section, you can monitor and inspect the individual functions. Internal measurements: 165 x 243 mm. Inspection light (Item number ) Light is essential, if you would like to inspect each section s functions. For large air handling units where you need to go inside, it is also an essential safety factor. If the air handling unit is delivered with control system or Controller Ready, an LED light, 24V, is used. (Item number ) (Item number ) If the air handling unit is delivered without control system, an LED light, type GX53 with 230V socket, is used. (Light: item number , socket: item number ).

18 Spare filters You can choose between 3 types of filters for your Geniox air handling unit: Panel filters, bag filters and metal filters. Your choice of filter depends on the job. The higher the filter class you choose, the more/smaller particles are filtrated. On the other hand, they need to be replaced more often and may result in a higher pressure loss. Synthetic material, panel filters Coarse 65% (G4) Glass fibre material, bag filter epm10 60% (M5) epm2.5 50% (M6) epm1 60% (F7) epm1 75% (F8) epm1 85% (F9) Glass fibre and broad spectrum carbon media, bag filter CITY-FLO epm1 60% (F7 City-Flo). To ensure continuous operation without stop, it is always a good idea to have a set of spare filters at hand. If you do not, you run the risk of the filters being removed in order to buy new matching filters. You can choose between panel filters and bag filters. Panel filters are pleated and designed in synthetic polyester fibres. The frame is made of cardboard. Bag filters are designed in glass fibre material. The filter frame is made of plastic and the filter is sealed between the filter cells with rubber sealing strips. You can also get CamMet metal filters to use as e.g. prefilters to collect fat from a cooker hood. The filter cells are designed in aluminium thread. The filter is class G2 and washable. The filter can be cleaned with a water pressure cleaner. The frame is made of aluminium. The thickness is 40 mm. 18 systemair
