Upblast Centrifugal Roof Ventilators

Airmaster CDU Series direct drive centrifugal upblast / wall fans are used in kitchens, restaurants and food service establishments to remove smoke, odours and excess heat for a clean and comfortable environment. These ventilators have a high vertical discharge design to prevent air recirculation and ensure safety with an emergency disconnect switch. They feature a non-overloading, backward inclined wheel for consistent airflow. These units allow customisable operation through standard variable speed control. They come with rubber vibration isolators for quiet performance and have a compact size for ease of installation.

Dayton hazardous-location upblast centrifugal ventilators are roof-mounted for continuously discharging hazardous chemical fumes & particles, dirty air, grease, foul air and odour from industries and commercial buildings. They have spun aluminium housing with backward inclined, spark-resistant aluminium wheels for corrosion resistance, durability and overload prevention, regardless of static pressure applied to the system. They feature belt-drive motors for greater flexibility in terms of rpm speeds, as the motor is not directly in contact with the fan's moving parts. Choose from a wide range of these ventilators, available in wheel diameters ranging from 11.25 to 18.50 inches.

Dayton wall mounted, belt-drive upblast ventilators are used for exhausting contaminated air, fumes, odour and grease-laden particulates from kitchen range hoods and cooking appliances. These units are ideal for applications in schools, restaurants, commercial and industrial facilities. They feature a fully rolled aluminium windband (welded to the base) for creating a leakproof seal between the ventilators and the mounting surface and have aluminium housing for corrosion resistance. They also include neoprene studs to isolate the motor, drive frame and the blower wheel from the mounting base to prevent vibrations and noise. Choose from a wide range of these belt-driven upblast ventilators, available in wheel diameters ranging from 11.25 to 30.50 inches.

Dayton upblast ventilators are roof-mounted for discharging dirty air from industries and commercial kitchens. They are designed to operate continuously to vent grease, foul air and odour under low to moderate static pressure conditions. They have spun aluminium construction with a fully rolled windband to increase corrosion resistance, durability, stability, portability and withstand a maximum inlet temperature of 300 degrees F. These ventilators feature belt-drive motors that offer greater flexibility in terms of rpm speeds as the motor is not directly in contact with the fan's moving parts. Selected models come without assembled drive packages for optimising the ventilators according to specific applications. Choose from a wide range of these ventilators, available in wheel diameters ranging from 11 to 24.5 inches.

Dayton direct driven upblast ventilators are manufactured to take out fumes, odour, foul air and grease-laden vapours in the facility. They are equipped with a variable speed motor and feature electronically commutated motor (ECM) technology and a potentiometer dial mounted on the motor to manage speed. These upblast ventilators permit up to 80% useable turndown remove the requirement for speed control. Choose from a range of these upblast ventilators, available in 1 and 3 phase options.

Dayton assembled upblast ventilators are ideal for use in schools, restaurants and commercial & industrial applications to exhaust out foul air and smell. They come with internal steel support braces and a fully rolled windband to improve the rigidity of the ventilator for superior stability while installation and transport. The motor compartment of these vents are confined from the contaminated air stream and cooled by outside air that is pulled-in through an oversized breather tube. Choose from a range of these upblast vents, available in 1 and 3 phase options.

Dayton upblast ventilators are roof-mounted for exhausting heat and grease-laden effluents from commercial and industrial kitchens. These units feature a fully rolled aluminium windband that creates a positive leakproof seal between the ventilator and the mounting surface. In addition, these windbands along with internal steel support braces offer great rigidity and stability during transportation and installation needs. They have independent neoprene studs to keep mounting bases isolated from the motor, drive frame and wheel components. These upblast ventilators feature belt-drive mechanism for flexibility in speeds and motor selections ranging from 735 to 1050 rpm and 3/2 to 3 hp, respectively. Selected models come unassembled for optimising the ventilators as per the application requirement.

Dayton upblast ventilators are used for exhausting contaminated air, fumes and odour from commercial and industrial kitchens. These units feature leakproof seals to prevent ingress of contaminants and have internal steel braces w/ a fully rolled aluminium windband to increase rigidity and allow greater stability during shipment & installation. Neoprene studs fit in between the assembly (motor, drive frame and wheel) to avoid metal to metal contact and significantly reduce overall noise. They also feature NEMA 1 junction box to protect wiring connections and roof curbs to provide easy installation. Choose from an array of these belt-drive upblast ventilators, available in 34, 42 and 46 inch base lengths.
