EXAIR

EXAIR air guns, such as the adjustable pocket-grip model MPN 1928-6 and the pistol-grip model MPN 1690-6-CS, are constructed from cast aluminum. This material provides durability and corrosion resistance in industrial environments. Some accessories, like extension pipes, are also cast aluminum. For applications requiring non-magnetic or higher corrosion resistance, EXAIR offers stainless steel options in other product families, such as shim sets (e.g., MPN 110309SS).

EXAIR vortex tubes, like the MPN 3204, use compressed air as a power source. Air enters the tube tangentially, creating a vortex that separates into hot and cold streams. The cold air exits one end, while hot air exits the other. This design has no moving parts, making it reliable for spot cooling in control panels, machining operations, or electronic enclosures. The MPN 3204 has a maximum flow rate of 4 scfm and a cooling capacity of 275 BtuH, with adjustable temperature from 28°F to 129°F.

EXAIR stay-set hoses, such as the MPN 9224, are designed for mounting and bending toward a specific application. They allow operators to position airflow precisely without needing clamps or brackets. The hose holds its shape after bending, enabling directed cooling, drying, or cleaning. The MPN 9224 has a 24-inch overall length and is compatible with EXAIR air guns and nozzles. This flexibility reduces setup time and improves targeting in confined spaces.

Yes, EXAIR air knives, like the 48-inch model 112048, can be adjusted using shim sets. The shim sets, such as the stainless steel 110309SS or polyester 110342, are placed between the knife body and the slot to change the air gap height. The standard slot height is 0.002 inches, but shims allow for wider gaps to increase flow or reduce velocity. This adjustability lets users fine-tune performance for specific cleaning, drying, or cooling tasks without replacing the entire knife.

EXAIR air guns, such as the pistol-grip model MPN 1690-6-CS, include safety shield extensions to protect operators from debris or chip deflection. The ergonomic grip reduces user fatigue, and the cast aluminum construction withstands industrial use. Many models also incorporate a dead-end pressure relief feature, which limits output pressure if the nozzle is blocked, complying with OSHA standards. The MPN 1690-6-CS has a 1/4-inch female NPT connection and a straight extension pipe.

EXAIR shim sets, like the 110309SS (stainless steel) and 110342 (polyester), are used to adjust the air gap height on air knives. By inserting shims between the knife body and the slot, users can increase the gap from the standard 0.002 inches to a larger dimension. This increases airflow volume but reduces velocity. The choice of material—stainless steel for high-temperature or corrosive environments, polyester for general use—affects durability. Proper shim selection optimizes the air knife for specific tasks like drying or cleaning.
