Why is the Binks MACH 1SL spray gun still so popular?

There are many spray gun manufacturers who do supply HVLP spray guns. Well-established and high quality manufacturers include IWATA (Japan), Graco-Sharpe (USA), Fuji (USA), Sata (Germany), Walther Pilot (Germany) and Krautzberger (Germany). In addition there are the low quality Chinese-made spray guns which can be found in almost every hardware shop and are also marked as “HVLP” compliant (however, most of them are in fact not). But there is one particular spray gun which was invented over 15 years ago and be considered as the forerunner of HVLP: The Binks Mach 1SL (“SL” stands for Slim Line). It is the successor of the legendary Binks BBR gun.

Mach 1SL – The features

The Mach 1SL is exceptionally rugged in construction. P.T.F.E. packings are used throughout the gun which are resistant to all known paint solvents. The whole gun weighs only about 448 grams due to the drop-forged aluminum body. The self-aligning needle control and air valve are combined in order to reduce components. But one of the main reasons why this gun is still one of the best choices for applications like adhesive, agricultural, aviation & aerospace, corrosion control and general metal is the fact that it offers one of the largest selections of nozzle and air cap (air nozzle) combinations.

There are standard fluid nozzle sizes from 0.5mm to 1,7mm (nozzle types 89 to 97). And basically all nozzle sizes can be operated with one type of fluid needle. This is a major advantage compared to many other spray guns where the change of nozzle also means a change of needle. In the beginning the needles AB and ABSS (54-3609 & 54-3616) were used, but those required readjustment of the needle cap and lock nut position. Today there is one single-piece needle ABSL (54-4382).

Nozzles for Special Applications

In addition to the standard nozzles and the so-called GS fluid nozzles (from 1.2mm to 1.7) there are special purpose nozzles available: nozzle sizes of 1.3mm to 2.8mm (nozzle types 901-909) can be used for very heavy fluids, optionally these nozzles come with carbide tip (marked with VT). For applications requiring more gradual fluid valve opening for metering control of the fluid flow with the trigger (feathering) the “F” range of nozzles between 0.8mm to 1.7mm (nozzle types 90F-97F) are available. The nozzle range is round off by the “S” range which is used in connection with a siphon cup (suction feed). These nozzles can then be combined with more than twelve (12) different kinds of air caps, each with specific nozzle air flow and pattern width. Part numbers for the air caps and nozzles can be found in the Mach 1SL nozzle & air cap part number guide.

Application: from refinishing paints to glazes

This wide range of nozzles and air caps allow a very good atomization of virtually any coating. Therefore the Binks MACH 1 SL HVLP spray gun can spray all conventional and the more unconventional materials encompassing refinishing paints, industrial finishes, adhesives, decorative materials, stains, inks, varnishes, lacquers, enamels, glazes water-borne materials and many others.
