The Dyna-Fog Twister XL, powered by Tanaka-Purefire, is currently the very first and only 2-cycle engine approved to meet the rigid California emissions standards for 2-cycle engines through 2000.
The Twister XL™ is an aerosol generator designed to take the stress and weight off of the operator's wrist and hand to ensure comfort and ease when operating the unit. The Dyna-Fog Twister XL is perfect for controlling gnats, mosquitoes and other flying insects. The variable chemical output capability is one feature that makes the Twister XL™ suitable for all operating situations. Through use of the optional 2-nozzle kit, high outputs can be attained in conditions where a fast application is needed (such as swine and poultry houses). Another feature of the Dyna-Fog Twister XL is the ability to direct the high output to only one nozzle, resulting in droplets being produced which are suitable for leaving a residual deposit on surfaces such as walls and vegetation (for instance, barrier spraying for flies and mosquitoes).
The Twister XL™ is powered by the Tanaka Purefire engine, a completely new design of a 2-cycle engine, delivering unsurpassed fuel efficiency, along with a level of emissions so low that it exceeds all current or anticipated emissions regulations for hydrocarbons.
When used at the recommended flow rates, the Dyna-Fog Microtec™ nozzles will produce 90% of the droplets below 20 microns. This meets all current chemical label requirements for controlling flying insects. When the high flow rate is discharged through a single nozzle, the Twister XL™ will produce larger droplets of 50 microns, which are suitable for applying a residual deposit to walls, vegetation and any other surface.
The Twister XL™ is constructed using the highest quality materials with stringent quality control throughout all stages of assembly. The Twister XL™ is coated with chemical resistant epoxy paint, resulting in reliable usage with a minimum of maintenance.
Over 50 years of experience has gone into the design, development and production of the Twister XL™, the latest addition to the Dyna-Fog family of ULV applicators.
The Twister XL™ is backed by Dyna-Fog's 1-year warranty and a worldwide support network of factory trained technicians and experienced distributors.
Standard Features:
- Safety feature - engine quick cut-off switch
- Powered by a two-cycle Tanaka PureFire™ engine. The novel crankcase, cylinder and piston delivers 30% more fuel efficiency than other 2-cycle engines, along with 70% less emissions - exceeding the most demanding emission standards currently in place or anticipated (including the California Air Resources Board Tier II).
- Engine mounted on anti-vibration pads for operator comfort.
- All formulation controls right by the operator’s hand.
- 3-stage high output rotary blower.
- Single nozzle delivering an exact droplet size for optimum results.
- Small frame size and adjustable padded shoulder and waist straps to suit all body sizes.
- Nozzle arm holder on frame to prevent damage when not in use.
- For operator comfort, no trigger to hold, and minimal weight on operator's hand.
- Visual warning pennant on 26″ (66 cm) telescopic, flexible mast.
- Welded tubular aluminum frame.
- Welded tubular aluminum frame.
- Supplied with fuel mixing beaker and funnel.
- Chemically-resistant epoxy paint.
- Flowmeter to determine the viscosity value of individual formulations.
- 1-year warranty
Optional Extras:
- Twin Microtec™ nozzle kit (P/N - 39716) for high outputs in time-restricted conditions as well as other situations.
