![]() In order to efficiently cool a room, the blower CFM should be chosen while considering the room space / size. What does the CFM rating of a Venturi blower signify?Ĭubic Feet per Minute or CFM represents the amount of air that can be moved through a room when operating a blower / fan at the highest speed. These blowers should also be weight, vibration & motion mitigated for secure operation. Yes, they can be installed vertically above tanks, manholes or other locations by supporting them with proper ingress & egress accessories. Can Venturi blowers be mounted vertically on tanks? They are also suitable for extracting fumes or toxic air that are generated in a specific location. Venturi blowers should be used for positive ventilation in confined spaces. Is it better to ventilate or extract air using Venturi blowers? Yes, using two Venturi blowers in the same space would increase the concentration of fresh air in the space, though the overall air exchange rate would not increase significantly. Can I use two Venturi blowers in the same space, one to ventilate and another to extract air? The biggest reduction in output occurs after the first addition of ducting or bends, thereafter the drop is much smaller. The number of bends and length of ducting attached to a Venturi blower adversely affect its output. Several factors can affect the total output of a Venturi blower. What is the effect of ducting on the output of a Venturi blower? Statically conductive ducting can handle temperatures up to 250 degrees F. The maximum working temperature that a standard ducting can withstand is 180 degrees F. What is the maximum temperature that a ducting can handle? Allegro Venturi blowers are also available in plastic construction for light weight and durability. Raptor Supplies delivers Allegro 9518-08 Venturi blower in variants having air consumption ranging from 50 to 380 scfm at 100 psig inlet pressure.Users can also select statically conductive ducts for preventing static electricity from building up in the unit. These yellow coloured ducts have a black wearstrip and meet ASTM 227 standards for safe operation.It can supply air through ducts having single ply, PVC coated vinyl & polyester construction with Class 1, hard drawn spring steel wire helix for a retractable, non collapsible design and temperature resistance up to 180 degrees F.This Venturi blower is equipped with a crow's foot inlet connection for secure hose / inlet pipe connection.It can be operated at a maximum inlet pressure of 140 psi.This pneumatic blower does not require protective grills as it can handle impacts without getting damaged.The Venturi blower design features plastic handles for conveniently carrying the unit from one place to another, by a single person.The inlet housing comes with a static ground connection for preventing short circuiting in hazardous locations.It has a galvanised steel diffuser & a cast aluminium base for strength, light weight and corrosion resistance in abrasive / outdoor environments.This venturi action helps in throwing out large volumes of air through an air diffuser & clearing away harmful gases.It is powered using compressed air or saturated steam through an inlet hose to create a Venturi or pulling action.Allegro 9518-08 Venturi blower is used to circulate air in hazardous areas and confined spaces.We also supply related products like air powered confined space fans & blowers, explosion proof blowers and jet fans for circulating air in hazardous areas or confined spaces. It produces 77 dB noise at a distance of 5 feet & an inlet pressure of 60 psig. It does not have any moving parts and does not require protective grills as it can withstand impacts & external stress / damage. Its 1 inch NPT inlet connects to an air supply hose for consuming 180 scfm air at 100 psig inlet pressure. They are generally powered by compressed air or saturated steam.Īllegro pneumatic blowers are equipped with a crow's foot inlet connection for securely connecting a hose to an air supply source and static ground connection in hazardous locations to prevent short circuits.Īllegro 9518-08 Venturi blower has a base diameter of 14.37 inches and a diameter of 14.25 inches at the top of the air horn, providing an airflow of 5435 cfm. These Venturi blowers also clear away explosive or hazardous vapours from confined spaces in refineries, power plants, shipyards and other industrial environments. Confined space Venturi blowers are ideal for delivering and circulating cool air in spaces where heavy equipment is at risk of overheating. ![]()
