Pitot Tube Anemometer TA400 incl. Cal. Certificate With the TA400, you cannot only measure even extremely high air velocities up to 80 m/s, but equally also the ambient temperature and air volume flow. The cross-sections of the air ducts to be measured - whether round or square - can be entered into the device in a differentiated way. Technical details:- Air flow velocity Measuring range: 1 - 80 m/s; 3,6- 288 km/h; 200 - 15.733 ft/min; 2,24 - 178,66 mph; 2 - 154,6 kn - Air flow velocity Accuracy: ± 2,5% at 10 m/s - Air flow velocity Resolution: 0,01 m/s; 0,1 km/h; 1 ft/min; 0,1 mph; 0,1 kn - Air/ gas pressure Measuring range: 0 - 5.000 Pa - Air/ gas pressure Accuracy: ± 0,3 % at +25 °C - Air/ gas pressure Resolution: 1 Pa - Air/ gas pressure Measuring units: PA, mbar, psi, inH₂O, mmH₂O - Air temperature Measuring range: 0 - 50 °C (32 - 122 °F) - Luftemperatur Accuracy: ± 1 °C (± 2 °F) - Air temperature Resolution: 0,1 °C (0,1 °F) - Volume flow Measuring range: 0,001 - 99,999 m³/min (CMM) ; 0,001 - 99.999 ft³/min- Volume flow Accuracy: ± 0,3 % of the measured value- Type: dynamic pressure probe - Type of construction:Pitot tube in L-form - Length: 335 mm - Ø Probe tip: 8 mm - Hose length: 850 mm - Storable measured values: 99 - Operating conditions: 0 °C up to +50 °C, < 90% r.h. - Dimensions: 210 x 70 x 50 mmp> - Weight: 540 g (incl. battery and probe)p> - Power supply: 9 V IEC 6LR61 - Scope of delivery: Measuring device with instructions, calibration certificate, batteries, USB cable, software, hard top case, pitot tube, 2x silicone connection hoses (length 850 mm)
4" (100mm) Cowled Vent Wind Baffle Grille Ideal for mounting on an external wall that is in an exposed position and where an outlet will be open to bad weather. The baffled grille has two advantages; it stops wind from rattling the shutter and also stops back draft when an extractor fan is switched off. Ideal for wind and rain protection. 100mm (4") diameter duct connection that fits standard ducting or wall sleeves. Single blade damper for anti back draught. Easy screw fixing and connection to ducting. Duct cowling baffle and blade are easily removed for fitting & cleaning. We have updated our colour range for external cowled grilles to suit traditional building materials such as terracotta and cotswold stone (beige). We have also included colours to suit more modern architectural designs like grey and black. Grilles can either discreetly blend in offer a contrasting look. White. Brown. Black. Grey Cotswold Stone (Beige). Terracotta.

As seen on episode 5, series 16 of Dragon's Den.The DR21 anti-draft air vent is a new design which allows air necessary for combustion to be drawn into the room, but stops air being blown in. This ensures you can enjoy your stove in comfort.The DR21 frees your living room from annoying cold draughts being blown in, especially when the stove is not in use. It also eliminates insect-attracting light emissions, and can be used in place of underfloor air vents, or to replace rattling air vents in a bathroom. The DR21 anti-draft vent is as easy to fit as a standard louvred vent cover, costs about the same as a bag of wood, and pays for itself in reduced heating costs. If you already have a louvred vent installed, you can switch it out for a DR21 anti-draught air vent in just a few minutes. Fits standard 4" (10cm) hole - and can cover a 125mm hole or even a square clay air vent. Unit dimensions: 22cm x 22cm x 18cm Unit weight: 320g Box includes: top and bottom sections of air vent. You provide: screws, sealant, glue, ducting, vent cover for inside house. HETAS approved for throughput equivalent to 3400mm² of free air.
Heat exchanger (originally recuperation in Latin receiving back, returning) is an energy saving device designed to save thermal energy through heat recovery. As of today thermal energy recuperation is one of the basic energy saving technologies and an integral part of ventilation systems in modern buildings and premises. The passive heat exchanger PR 150 installed in ventilation systems serves to transfer heat or cold from extract air flow to intake air flow from outside. Recuperation minimizes thermal energy losses and reduces operating costs for warming up of supply air in cold seasons or for cooling down in hot seasons. The passive heat exchanger PR 150 is designed for joint operation together with supply and exhaust in-line fans, as for example, VENTS VK 150. The heat exchanger is installed behind suspended ceiling and connected to Ø 150 mm ductworks. The high-efficient heat exchanger is made of polystyrene or aluminium and ensures recuperating efficiency up to 90%. The heat exchanger has a compact and small casing made of alu-zinc internally filled with thermal- and sound-insulated layer. The built-in replaceable G4 filters are designed for purification of supply and extract air. Ventilation system with heat recovery means not only clean air in your house but a considerable money saving.

Preferred choice for MVHR heat recovery systems. Disc is mounted on a central threaded core for adjustment that can be locked to prevent tampering. Can be used for extract and supply air ducts. This Air Valve is perfect for finishing off any ventilation or heat recovery system to a high standard. Finished in a highly reflective chromed plastic, that will match chromed elements in a bathroom, wet room, kitchen or cloak room. Air valve vent grilles are easy to for and connect to standard size 100mm (4"), 125mm (5"), 150mm (6") and 200mm (8") duct, ventilation or heat recovery system. easy to commission (when setting up and balancing a centralised ventilation system) and adjust for fine tuning. A locking nut is included so when optimal airflow and noise control is achieved, you can simply lock the central cone to set to prevent any future tampering or adjustment. Alternatively, simply spin the central cone to deliver more or less air to suit any bedroom, living room, bathroom or kitchen.
