All Ozone Ventilators are equipped with an impressive array of standard features: -
Connections for both outlet and inlet hose - equally suited to blowing fresh air into or extracting polluted air out of a confined space. -
Finger-proof mesh guards on inlet and outlet. - Removable spigots, with various diameters available. Ventilators with just the one spigot attached are compact and easy to handle. -
High pressure centrifugal rotors. - Polymer-coated, genuinely industrial design. CC4, KH200 ? Reflective safety strips for roadside utilities.
The unique CC4 Ventilator features a fully enclosed combustion motor. Coupled with heavy duty isolation feet, the motor is fully protected from the typical knocks and bumps caused during transportation and site work. All the components are located inside the case.
Strength and reliability are matched by its heavy duty performance. The high flow and high pressure design rotor generates exceptional air flow, even through long lengths of small diameter flexible hose. The 2 metre long stainless steel manifold hose keeps exhaust gases away from the clean air intake.
Electric Models CX3, CX4, CX6
Ozone has set the new benchmark in confined space ventilation by combining the best features of both. The patented dual flow system allows the Ventilator to be easily converted to either inline flow (compact and quiet) or right angle flow (motor out of the airstream). Either way, the motor remains fully protected within the rugged case.
The Ozone Canister stores a full 5m of 150mm compressible hose. The cuff on the end of the Canister simply slips over the Ventilator spigot. The Canister is easily removed from the spigot, to carry it in one hand and the Ventilator in the other. The Canister pays for itself with increased productivity, portability and longer hose life.
Thanks to the interchangeable spigots, ventilation systems can be tailored to suit any application. For instance, the SD150 accessory allows two inlet or outlet hoses to be connected simultaneously.
What are the differences between centrifugal and axial ventilators ?
Axial products are compact, with the motor enclosed within the case. They deliver good flow rates, but only through large diameter (eg 300 mm) hose. Often this means having to remove the hose from the confined space entrance whilst personnel move in and out, which is not a safe work procedure.
As the motor is within the airstream, axial products are not suitable for extracting explosive, flammable or corrosive pollutants. Because of their low pressure, the flow stops if the hose is "pinched".
Traditional centrifugals work with smaller hoses with the motor located out of the airstream. However the motor is not protected and is easily damaged.
Pneumatic Model CP3
The compressed air driven CP3 is intrinsically safe and is also conductive for dissipation of static charges. The advanced design is vastly superior to conventional air driven motor/rotors as there are absolutely no moving parts. No risk of bearing sparks or particulate sparking on rotors. No maintenance necessary. No oiling requirements and no danger of over-pressurising. Ozone Low Static Hose is lightweight and very flexible. Being carbon impregnated it has much higher static protection than hoses with internal earth wires. Unlike coated hoses, its conductivity remains high over its lifetime. Other accessories include the EP5 Controller (with filter and regulator), for the supply air, and the EL3 Ohm meter to check your system.
Snorkel NL150
Couplings, Kits and Hose
The Ozone Snorkel is a critical component where access into the confined space is restricted. The profiled shape takes up a mere 100mm of space, whilst the smooth surface ensures operator’s apparel does not become caught.
The unique design incorporates four alternate inlet/outlet holes, allowing the system to suit the application and to minimise hose bends.
Screw-on polymer Hose Cuffs are available in various sizes and guarantee a perfect seal. Ideal for off-site work where hose has to be removed on a regular basis. Magnetic Hose Kits are available for extracting pollutant, such as welding fume, at its source.
Four grades of flexible hose add to the versatility of the Ozone range. Regular Duty is compressible and commonly used for blowing fresh air. Heavy Duty hose is typically used for extracting welding fume. Low Static hose is genuinely conductive, whilst the 250°C rated Thermal Duty hose is suitable for hot surfaces.

Technical and Safety notes
1. When blowing, locate hose outlet/s near the operator/s and generally 300mm above floor. This helps avoid short circuiting of fresh air supply. Locate inlet of all Ventilators upwind and/or a reasonable distance away from the space opening. (Connect hose to Ventilator inlet, if necessary). If using model CC4, also connect manifold hose and locate its outlet downwind of Ventilator and away from space opening. These practices help avoid displaced gases from confined space or exhaust gases from manifold being recirculated back to Ventilator inlet. 2. Monitoring procedure: (a) monitor/test the air before ventilating, (b) begin ventilation far enough in advance so the air will be safe before entering, (c) monitor/test the air just before entry, (d) during occupancy continue ventilation and monitoring/testing. 3. Use model CP3 with HL150 and UK150 if intrinsic safety required. Use Heavy Duty Hose if welding. Do not position model CC4 in hazardous area or inside a confined space. If using electric models, and extracting potentially explosive/corrosive/hot pollutants, then configure to right angle flow (so motor out of airstream), ensure no particulate enters the inlet, and fit both inlet and outlet hose. 4. If requiring a low static system: order low static hose, electrically bond between ventilator/spigot/hose/snorkel/confined space at all connections, then earth. Check bonding/earthing periodically with Ohm Meter. 5. Read Instruction Manual provided before operating products. 6. Any request for non-standard Ventilators or Ventilators to be used in hazardous areas or with pollutants which are explosive/flammable/ combustible, must be clearly stated in writing on customer’s final order and, if accepted, will be restated on Ozone’s invoice. 7. It is impossible to list all the potential safety issues associated with ventilation. Ozone is a supplier of standard products: not a consultant or contractor. We rely on the customer and their agents to safely select products, design connected systems, and install/operate/maintain these products and systems to suit their pollutant. Customers should consult and comply with all National and State laws/regulations/ standards. 8. Extractor patents are pending.
