Plastic Ventilation Ductwork Guide. Find out what is a chemically resistant ventilation system, where can You use it and what types of ventilation ducts are available. Learn how join and install plastic ducting. Select correct material and check its chemical properties.
Do You know that You can join PVC vent pipes using special glue? To be precise You can glue ventilation pipes and fittings up to a diameter of 250mm. Glueing is a popular method of joining PVC ventilation systems because it's rather simple and requires no special tools as in the case of extrusion welding or wire welding (see How-to: Welding plastic ventilation ductwork). However, in order to make a solid and tight joint of PVC pipes and fittings, we must properly prepare the duct components for the process of glueing and follow the recommendations of the special glue manufacturer. Find out How to properly glue PVC ducts and fittings - Read our Manual!

The DM-ML / DM-FL actuator enables remote operation of a ventilation damper. The actuators with 5, 6 and 8 Nm of torque are the most popular choice for ventilation dampers. The torque of 6 Nm allows opening dampers with the crosssectional surface area up to 1.5 m2; they can be installed on ventilator dampers up to 400 mm in diameter. The DM-ML -...- S actuator has an additional limit switches, which can signal the damper position in the range of 0-10-80-90. Precise, variable control of damper position is obtained by mounting the DM-ML -...- RS actuator, which operates by means of current signal 0 (4) -20mA or voltage signal 0 (2) -10V.
