The air powered airless model rhino has been designed to withstand toughest working conditions as can be found at shipyards, steel construction plants, freight car manufacturing plants, or bridge building sites.

Rhino pumps come in various versions: hydraulic pressures up to 450 bar corresponds to relative transfer volume up to 550 cc /cycle so that even with several spray guns and long material hoses considerably high spray pressures can be obtained.

Rhino pumps are in Stainless Steel 410 and also available in high quality steel versions (SS 304, SS 316, Food Grade, etc) on customer request. These pumps are also available as stationary units for wall mounting.

Ambient temperatures are sufficient for traditional airless cold spraying.

If, however, highest requirements are to be met with view to economy, working hours, film thickness, regularity and evenness of the coating, airless cold spraying will not suffice unless one implies its alternative: airless hot spraying. This method is particularly suited for materials that will not yield satisfactory results when being used cold. For example, a highly viscous synthetic resin varnish can be applied with the cold airless system at 180 bar with unsatisfactory results. After heating the material up to 80°C, it can be used at 40 bar yielding an even and regular coating.

In comparison with airless cold spraying, airless hot spraying means a cut in solvents. Even the most viscous materials spray without solvents at 40 bar pressure when sufficiently heated.

All airless hot spraying units are available with high pressure filter, material hoses, hand spray guns, and airless nozzles. All units are corrosion resistant.

Inline paint heater is the integral part of airless hot spraying unit. It is flameproof version as per IS 2148-1981 and weather proof protection IP55.as per IS 13947-1993

The Airless Plus system performs a two fold function: conventional compressed air spraying and airless spraying at a time. Spraying materials such as paint, lacquer, or stripping agents are applied by an airless spray gun being equipped with fine adjusting air nozzles to assist the spray jet on either side. Besides an improved spray pattern the airless plus system offers following advantages:

Superb surface quality and negligible orange peel effect.

Upto 20% material economy compared to ordinary airless systems, because optimum atomisation reached at low material pressure.

Using combined compressed air and airless spray results in an almost entire suppression of rebouncing spray mist. This system also permits positive spraying of grooves, recesses and sinkings.

No side runs when using highly viscous materials.

Our Airless Plus units are available in portable mobile and stationary version with large type high pressure filter, high pressure hose, Airless Plus gun and nozzle. All wetted components are made of stainless steel 304. For the Airless Plus system, we suggest the following types of airless pumps:

Hippo 4.90 : For low viscosities and average flow rates (stains and transparent lacquers). Airless Plus only.

Tiger 12.150 : For low and average viscosities at high flow rates (stains, transparent lacquers). This pump also qualifies for manual and automated installations using one or more spray gun: it is less suitable for pure airless spraying.

Tiger 28.40 : For low and average viscosities at low flow rates (stains, transparent lacquers, cellulose lacquers, primers, pigmented lacquers). Suitable for both airless and airless plus.

The air spray gun uses air at 2 to 6 bar to atomize the paint into a fine spray. This produces a smooth finish, and can be used on many surfaces. Air spraying is versatile; the operator can vary their pressure, air volume, paint pressure, and spray pattern. With a transfer efficiency of 30 to 60%, air spraying produces a lot of over spray (the paint that missed the intended target) causing preparation and clean-up to take more time.

A High Volume Low Pressure (HVLP) spray gun uses higher volume of air at only 0.6 bar. This reduces the over spray, increasing the transfer efficiency. An HVLP gun is portable and easy to clean, and has a lower risk of blowback to the worker. However, the atomization may not be good enough for fine finishes, and production rates when using HVLP may not be as high as with conventional spraying.

V R Coatings does not manufacture spray guns for these applications but provides suitable pumps and other accessories for this application.

Hippo 1.170 the diaphagram pump is suitable to feed two air spray gun without pulsation with accessories like low pressure filter, regulators etc.

Hippo and elephant range of pumps are used to feed air spray guns

Hippo 3.400, 2.900, 5.900 these pumps are suitable for localized booth side paint circulation and to multiple air spray guns with accessories. Elephant range of pumps are used to feed centralized paint circulation and to multiple (in big quantity) air spray guns with accessories.
