BONOMI MUFFLER
Frequently asked questions
Common questions about BONOMI MUFFLER from 3G Electric.
What materials are Bonomi Muffler pneumatic exhaust mufflers and breather vents made from?
Bonomi Muffler SBM series exhaust mufflers and BV series breather vents are constructed from bronze. Bronze is selected for its corrosion resistance, mechanical strength, and suitability for use in pneumatic systems where exposure to moisture or contaminants is possible. The bronze body provides durability in industrial environments without the need for additional coatings.
What is the maximum operating pressure for Bonomi Muffler SBM exhaust mufflers?
Bonomi Muffler SBM series pneumatic exhaust mufflers are rated for a maximum operating pressure of 250 psig. This rating applies across all available NPT sizes (1/8 in, 1/4 in, 3/8 in, and 1/2 in). The pressure rating ensures the mufflers can be used in standard pneumatic systems without risk of failure under normal operating conditions.
What is the filtration rating for Bonomi Muffler BV breather vents?
Bonomi Muffler BV series pneumatic breather vents feature a 40-micron filtration rating. This level of filtration is designed to prevent particulate ingress while allowing air to pass freely for pressure equalization in reservoirs, gearboxes, and hydraulic tanks. The 40-micron element provides a balance between airflow and protection against contaminants.
What NPT thread sizes are available for Bonomi Muffler SBM exhaust mufflers?
Bonomi Muffler SBM series exhaust mufflers are available in NPT thread sizes of 1/8 in, 1/4 in, 3/8 in, and 1/2 in. Each size corresponds to a specific hex size: 7/16 in for 1/8 in NPT, 9/16 in for 1/4 in NPT, 11/16 in for 3/8 in NPT, and 7/8 in for 1/2 in NPT. This range covers common pneumatic port sizes.
What is the difference between Bonomi Muffler SBM exhaust mufflers and BV breather vents?
Bonomi Muffler SBM exhaust mufflers are designed for installation on pneumatic valve exhaust ports to reduce noise from compressed air discharge. They are rated for 250 psig and do not include filtration. BV breather vents are intended for use on enclosures such as hydraulic tanks or gearboxes to allow air exchange while filtering incoming air to 40 microns. BV vents are rated for 150 psi. Both are made from bronze and use NPT threading.
