While today’s groomers have numerous equipment options and obligations to contend with, one of the most critical dryer categories is high-velocity dryers, a.k.a. blasters. As most groomers know, blasters generally have low to moderate air volume but high air pressure, allowing the discharge air to be concentrated through narrow nozzles to achieve high air speeds. The air also flows through and cools the motors, and as a result is heated—contributing to the drying process.
The importance of this dryer type has financial, ergonomic, and quality-of-work consequences.
The financial implications fall into several categories. A blaster is one of the few tools—aside from a clipper—used for relatively long periods of time, requiring hands-on labor. Accordingly, since a groomer’s time is his or her most valuable asset, a dryer’s effectiveness has an outsized impact on profitability.Virtually any two-motor high-velocity dryer on the market is a better investment than almost any single-motor unit, with labor savings paying for the difference in cost many times over before the end of the product’s lifecycle.
Relative performance differences among dryers from different manufacturers can also have significant financial implications. A performance improvement of only four percent for a dryer used just two hours per day, at a labor rate of €15 (or £15) per hour, can pay for the dryer within 18 months of ownership.
Serviceability is also important. Dryers engineered for easy serviceability can reduce expenses and aggravation associated with motor brush changes, repairs, and routine maintenance.
Ergonomically, noise, heat, and physical strain are all important factors to consider.
EU noise related regulatory guidelines are predicated on exposure levels measured in decibels (dB) over time. Eighty-five dB is generally considered the upper permissible limit. While the issue of acoustic insult can be complicated, it is best to invest in forced-air dryers that feature acoustically isolated motor/fan assemblies and sound-damping housing materials, which are typically quieter. Acoustically engineered nozzles and air intake systems can also help reduce noise.
Two-motor dryers can generate air temperatures up to 15° C above ambient. While this is very helpful for drying efficiency, it can be difficult to hold hot dryer nozzles for extended periods. Nozzles designed to insulate hands from high temperatures, along with thermally isolated handles, are best.
A dryer’s capability and versatility can affect—and improve—your finished presentation. Power, control, and the ability to modify airstream behavior can allow your blaster to strengthen your results and support your success.
