2 Flamco Flamco offers you a wide choice in the field of expansion vessels for potable water installations The use of Airfix expansion vessels offers the user a number of important advantages. Airfix expansion vessels are through-flow vessels, meaning that they are specially constructed so that they regularly rinse themselves with fresh mains water. In this way, still, stagnant water, which is associated with the formation of detrimental bacteria, is eliminated from the equation. This fact improves the quality of the drinking water. By using the Airfix A and expansion vessels, you can also limit water wastage. AIRFIX A The Airfix A expansion vessel enlarged here is supplied with a synthetic flow divider. This flow divider can be fitted between the standard T-piece (not supplied with the vessel) and the Airfix A vessel. The Airfix A expansion vessel and T-piece assembly can be fitted in the cold-water installation of the boiler and through-flow is established. 2 USER AVANTAGES AIRFIX A AN AIRFIX Very easy to fit. Covered inside and out with an anti-corrosion coating, both in the water half and the nitrogen half. Neither the diaphragm nor the coating give off any dye, smell or taste to the water; both have been approved by CE and the VGW (in Germany). Can be used with any storage water heater. Can also be used in pressure boosting systems.

3 Airfix -E Pressure expansion tanks with exchangeable diaphragms, suitable for use in hot-water, pressure boosting and water- AIRFIX AIRFIX -E AIRFIX -E-B management systems. The Airfix -E is a solid, stable tank which is easy to fit. It is a through-flow tank with two flange connections which has an exchangeable butyl diaphragm. The high-quality material of which the diaphragm is constructed is your guarantee of low permeability (which means that your gas will not leak away) and if used correctly, renders permeability negligible. Airfix -E tanks are fitted standard with an electronic diaphragm-rupture sensor and an internally-coated steel through-flow flange. USER AVANTAGES AIRFIX -E Complete through-flow from the tank, free choice of flow direction. Low pressure loss. The standard diaphragm-rupture sensor can, if so desired, be configured for remote reading device. Simple installation and long service life. The Airfix -E diaphragms come with a VGW certificate. Whichever Airfix vessel I choose, I know in advance that I m fitting quality. Airfix vessels are solid and have clever technological solutions to improve the through-flow of the water. In practice, they are the best choice for the specialist! Ensure that the double system connection is directly connected with the main flow in the potable water installation. 3

4 Flamco Logical Airfix technology offers the user signi Without an expansion vessel for sanitary appliances, the safety-valve (inlet combination) will leak water every time water is heated causing water wastage on each occasion. This significantly heightens the chance of lasting leakage as a result of pollution or calcium deposits building up in the area of the valve seat. This kind of serious water loss can now be stemmed by using an Airfix A or Airfix expansion vessel. AIRFIX All Airfix A and Airfix vessels are white in colour. Both diaphragm and vessel coating are internationally approved for use in combination with drinking water, meeting the CE standards (2002/16/EC). A reliable clamp construction which damages neither the vessel nor the diaphragm while allowing conservation of the entire vessel surface, something which is unthinkable in welded vessels without flanges. Airfix vessels use a special T-piece (supplied) which aids through-flow with its internal divider to ensure full through-flow in the vessel. An AirfixControl is fitted between the vessel and T-piece, enabling the Airfix vessel to be de-pressurized for maintenance work without the need for the installation to be put out of commission. The vessel pre-pressure must be 0.2 bar lower than the pressure in the cold-water installation or the pressure on the other side of the pressure-reducing valve. irections on how to fit the Airfix pressure expansion vessel Airfix A or Airfix expansion vessels should always be used with a Prescor B boiler valve. The vessel must be mounted in the cold-water pipe, between the Prescor valve and boiler. Airfix A or 4

5 ficant advantages The Airfix -E expansion tank can be used in pressure boosting systems, on either the intake or compression sides of the pumps. These installations are intended to prevent excessively low feeding pressure and help prevent excessive pressure changes at low flow speeds. At the same time, they reduce the number of times the pressure-water assembly needs to be switched. The Airfix -E expansion tank offers the precise solution for this. AIRFIX -E Inspection port (from 600 litres above and below). Pressure gauge with self-sealing valve case and an Rp 3 /8 IN connection to the tank itself. iaphragm-rupture sensor, basic appliance, display with red LE indicating diaphragm rupture. Maximum permissible gas prepressure on delivery: 6 bars. Maximum working pressures 10 and 16 bar. Airfix -E tanks are coated green. iaphragm-rupture sensor including signal cable. The Airfix -E diaphragm expansion tank has a gas space between the tank wall and the exterior of the membrane, and a water space within the diaphragm. The configuration of the gas space depends on the operating characteristics and the required pressure. A pressure boost in the water space will compress the gas volume and fill the diaphragm, while a reduction in pressure will lead to draining of water. Should the pressure in the gas space reach the set water pressure in the installation, water will be drained from the connection pipe. In all operating conditions, water flows through the tank with a very low loss of pressure. Airfix -E-L Airfix -E-B ouble system connection with through-flow function. For use in hot-water, pressure boosting and water-management systems. Airfix -E ouble system connection the link with the connection pipe. For pressure boosting, potable household, processing or fireextinguishing installations. Single steel threaded connection (without through-flow function) and without electronic membrane-rupture sensor. All materials used in this tank are potable water quality. 5

6 Flamco Airfix A and Airfix expansion vessels As long as the flow divider is not used, the Airfix A expansion vessel will function as a non-through-flow vessel. The pressure expansion vessels, when used in boiler systems, must always meet the requirements of the water board. The maximum temperature in Airfix vessels is 70 C.
