GUARDAIR

Guardair static-conductive vacuums are available with either ATEX or NED designations. ATEX-rated models conform to European Union Directive 2014/34/EU for equipment intended for use in potentially explosive atmospheres, and are marked accordingly. NED (No Evidence of Discharge) models are designed to prevent static discharge but may not carry the formal ATEX certification. Both types use conductive materials and grounding to dissipate static. The choice depends on the regulatory requirements of the installation site. For hazardous areas classified under ATEX, the ATEX-rated models are typically specified. For non-classified areas where static control is still desired, NED models may be sufficient. Always verify the specific model's certification and suitability for the intended environment.

Guardair pneumatic vacuums are offered with airflow capacities of 77, 129, and 149 cfm, depending on the model. Hose diameters include 1-1/2 inches and 2 inches. Air inlets are typically 3/8 inch or 1/2 inch FNPT. For example, the PQ55C150ATEX delivers 129 cfm through a 1-1/2 inch hose, while the PQ30C200ATEX provides 149 cfm through a 2 inch hose. The MV2000NED model has 77 inches of static pressure and a 1-1/2 inch hose. These variations allow selection based on the required suction power and the volume of material to be collected. Higher cfm generally indicates greater air volume movement, while static pressure indicates the ability to overcome resistance in the hose and filter. Consider the application's debris size and distance when choosing.

Guardair manufactures air guns and nozzles that are designed to meet OSHA standard 29 CFR 1910.242(b), which limits dead-end pressure to 30 psi. Many models achieve this through vented tips or pressure-reducing nozzles that allow air to escape if the tip is blocked against the skin. However, compliance depends on the specific model and its configuration. It is the responsibility of the user to ensure that the air gun is installed and used in accordance with OSHA requirements. Guardair provides technical data to assist with selection. For applications requiring full compliance, choose models explicitly rated for OSHA compliance and verify the dead-end pressure rating. 3G Electric can provide product documentation to support this verification.

Guardair ball-joint swivel air line fittings are constructed from nickel-plated steel. This material provides corrosion resistance and durability in compressed air systems. The fittings feature a ball-joint design that allows 360-degree rotation, which helps prevent hose kinking and improves maneuverability. Inlet and outlet connections vary: some models have 1/4 inch female NPT inlet and 1/4 inch male NPT outlet, while others have a male Industrial Interchange outlet. Pre-applied thread sealant is included on many models to simplify installation and reduce the risk of leaks. These fittings are suitable for use with compressed air and are commonly used at tool connections or hose ends. The nickel plating helps resist wear and environmental exposure. Always check the specific model's pressure rating and temperature limits before use.

Yes, many Guardair pneumatic vacuum heads are supplied as head-only units, designed to be mounted on a compatible drum or tank. This allows users to utilize existing containers, reducing cost and storage space. The head includes the motor, fan, and filter assembly, and requires a tank with the appropriate dimensions and sealing surface. Guardair offers heads for steel and polyethylene tanks. For example, the PQ55C150ATEX head is intended for a steel tank, while the MV2000NED head is for a polyethylene tank. When selecting a head-only unit, ensure the tank meets the head's mounting requirements and that the complete assembly maintains the static-conductive properties if required. Grounding of the tank and head is essential for static-conductive models. Consult the product manual for specific tank specifications.

Static-conductive construction in Guardair vacuums is intended to prevent the buildup of electrostatic charge during operation. When vacuuming dry powders, dusts, or flammable liquids, friction can generate static electricity. If a discharge occurs in a potentially explosive atmosphere, it could ignite combustible materials. Static-conductive vacuums use conductive materials (such as steel tanks and conductive hoses) and grounding paths to safely dissipate static charge to earth. This reduces the risk of sparking. Models with ATEX or NED designations incorporate these features. Proper grounding of the vacuum and operator is necessary for effective static control. These vacuums are commonly used in industries handling combustible dusts, such as pharmaceuticals, chemicals, and food processing. Always follow local regulations and the manufacturer's instructions for use in hazardous locations.
