ARROW PNEUMATICS

Many Arrow Pneumatics speed control mufflers, such as the ASP series, are rated to a maximum operating pressure of 300 psi. This rating applies to models with bronze construction and 40 micron filtration, including the ASP-1SCH, ASP-2SCH, ASP-3SCH, ASP-4SCH, and ASP-6SC. The pressure rating is a key specification for matching the muffler to the compressed air system's working pressure. It is important to verify the rating for the specific part number, as it may vary with port size and configuration. The 300 psi rating is typical for the speed control muffler family, but always confirm the individual product data sheet before installation.

Arrow Pneumatics exhaust silencers are available with NPT male connections in sizes such as 3/8 in, as seen in the ASQF-3M model. The ASQF-3M has a 3/8 in NPT male connection and a 1 in hex size, with an aluminum body and stainless steel element. Other sizes may be available in the broader product line. When selecting a silencer, match the NPT thread size to the exhaust port on the valve or actuator. The hex size indicates the wrench flat dimension for installation. For specific size availability, consult the product listing or contact 3G Electric with the required port size.

Arrow Pneumatics speed control mufflers typically feature a 40 micron filtration rating. This rating indicates the nominal pore size of the bronze element used to filter particulate matter from the exhaust air. A 40 micron element helps prevent contaminants from being expelled into the environment and can protect downstream components. The filtration rating is consistent across many models in the ASP series, including those with 1/8 in, 1/4 in, 3/8 in, 1/2 in, and 3/4 in NPT connections. For applications requiring finer filtration, alternative products may be available. Always refer to the specific product specifications for the exact filtration rating.

Arrow Pneumatics pneumatic mufflers use materials selected for durability and compatibility with compressed air systems. Exhaust silencers, such as the ASQF-3M, have an aluminum body and a stainless steel element. Speed control mufflers, such as the ASP series, are constructed from bronze. These materials resist corrosion and wear under normal operating conditions. The choice of material affects weight, temperature resistance, and service life. For example, the ASQF-3M weighs 0.06 lb, which is typical for a small aluminum silencer. When replacing or specifying a muffler, consider the operating environment and any chemical exposure that could affect the body or element.

To select an Arrow Pneumatics speed control muffler, first determine the NPT port size required for your pneumatic valve or actuator exhaust. Models are available in 1/8 in, 1/4 in, 3/8 in, 1/2 in, and 3/4 in NPT connections. Next, confirm the maximum operating pressure of your system does not exceed the muffler's rating, which is commonly 300 psi for the ASP series. Consider the hex size to ensure clearance for installation. The 40 micron filtration rating is standard for these mufflers. If you need assistance, provide the port size and pressure to 3G Electric, and we can help identify the matching part number, such as ASP-1SC for 1/8 in NPT or ASP-6SC for 3/4 in NPT.
