THE WIDE RANGE OFOstberg’s in-line Fan PRODUCTS
Circular fans100-800 CFMThe fans in this category all have circular duct connections. The CK is an in-line centrifugal duct fan with high capacity and excellent reliability available for both 230V/50 Hz and 220V/60 Hz.
Box and Rectangular fans from 700-8000 CFM
RKB is a range of straight flow in-line centrifugal duct fans designed for rectangular ducts. They are compact, high capacity fans which operate quietly and can be fitted in any position.RKB fans have backward curved impellers and are designed to cope with high pressure and long duct. The fans have a rigid housing made from galvanised steel. The motors are maintenance free and protected from overheating by thermo contacts. The impellers only require occasional cleaning. This cleaning is made easy with the RKB’s swing out design. All fans are supplied fully wired and ready to fit in a sealed installation unit.
The fans are not intended for transporting grinding dust, soot or similar. RKB fans come in 25 sizes.
Radial Fan
Our compact radial fans are principally intended for building into various units such as heat pumps, dehumidifiers and air purifiers. However, they can also be used as duct fans, The RF models have fan wheels with forward curved centrifugal impellers. The RB models have fan wheels with backward curved centrifugal.
Air flow up to 8,200 m3/h (2.28 m3/s).
This category comprises product groups with single extraction (RF), and double extraction (DF) units.

A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of an air-handling system or in the exhaust gases of an industrial process, in order to recover the heat energy. Other variants include enthalpy wheels and desiccant wheels

AC induction Motors –Geared motors

VacTech offers broad ranges of AC Induction Motor products with greater strength, longer life for various applications. Our AC induction motors meet all requirements of specific application in several different sizes and torque ranges.Induction motors are widely used for automation. Their simple construction and long life have earned them a place in an extensive variety of applications to power or drive industrial and business machines. There are broad ranges of models available for use with or without gear reducers. These motors are rated for continuous duty and are reversible.
Motors with Warm Gear Reducers
Motor-gear reducer is a viable alternative to electronic drives and is easy to use and maintain. Available upto 2,2 KW/Torque value 1,100 NM
ERV ( Energy Recovery Ventilators), HRV (Heat recovery ventilators)
These are effective in indoor applications that require 100-2000 CFM of air typically found in classrooms, meeting rooms ,retail outlets and villas.Theseare designed specifically for indoor installation and can be floor mounted or ceiling mounted.It is designed with enthalpy wheel or thermal plate type heat exchangers(PHE). A removable panel easily allows access to the enthalphy wheel /PHE and filters as needed.80 % effectiveness can be obtained and energy can be saved.
Benefits
- It provides clean indoor air. Energy savings provide exceptional payback.Initial cost savings can be achieved on main air handling units by reducing cooling load.Annual savings are achieved by preconditioning the outdoor air.
