Microbubble Air & Dirt Separator [PN 16]Flexair Supervent Max. 3/4″, PN 25 (1 no. required per Air Separator/ Microbubble Air & Dirt Separator of 300mm dia & Above) [SAVM-20]
Features
- Air separation process based on the concept of coalescence, microbubbles tend to adhere to a surface and then grow together to form larger air bubbles.
- Air separation process based on the concept of coalescence, microbubbles tend to adhere to a surface and then grow together to form larger air bubbles.
- – Large surface area per volume
- – High probability of collision and adhesion of microbubbles, as the fluid flow gets deflected in different directions
- – Minimal resistance to fluid flow
- High capacity auto airvent
- Separation of dirt particles heavier than water is facilitated by
- – Low water velocity
- – Deflection of fluid stream in many different directions by the Pall rings
- – Creation of non-turbulent zone in the extended lower part
- Ball valve at the bottom to drain the collected dirt particles
Benefits
- Removes air microbubbles
- – Increases heat transfer efficiency
- – Reduces chances of air lock
- Reduces corrosion in piping and sludge formation
- Removes impurities heavier than water
- – Prevents choking of strainers
- – Prevents damage to pumps and other equipment

Programmable
H3747
Product at a glance
The H3747 is a 4-channel smart programmer, which can control heat pumps, combi and system boilers, or even regular wired thermostats. Designed to supersede the ChannelPlus range by using the same wall plate with minimal wiring changes, whilst bringing connectivity features along the way. Out of the box, it is Bluetooth-enabled and works with a mobile app as well as the provided programable thermostat. With the optional plug-in Wi-Fi adapter, the H3747 can even remotely control your home heating system in a few simple steps. This unit is ideal for replacing traditional wired controls for systems that require separate control of heating and hot water or multiple heating zones. It is compatible with the standard 9-pin backplate offered with our popular ChannelPlus making retrofits and new installs an easy task. This smart programmer can even control the schedule of an existing wired thermostat and is designed to be modular and expandable with extra sensors for more heating zones. There is no hub or gateway to configure and power for remote access; simply plug the Wi-Fi card into the front slot, provide the password via the app and you will be connected. The H3747 also includes many of the latest Boiler Plus energy-saving features such as optimum start and stop per heating zone, as well as on-off load compensation. This significantly improves boiler efficiency by preventing short-cycling and overshooting of temperature and helps to save more energy and improve efficiency.

Mains operated electronic room thermostat
Mains powered electronic unit, with load compensation for new and replacement installations. Temperature setting range 5-30 °C. This is part of a range of purpose designed room thermostats, offering the latest energy saving control technology combined with established Secure design and manufacturing expertise. This makes them suitable for use in most types of heating systems that respond to a 230V mains electrical On/Off signal. They are also perfect partners for use with our range of programmers and zone valves. Designed to look good, these thermostats will outperform many older styles of thermostat and can often produce savings in the order of 10% over and above those achieved by traditional units using older technology. Temperature control accuracy of +/- 0.5°C and different settings (for gas, oil and electric systems) will reduce the temperature swing that normally occurs with older style
