Yes – our FM1 breather bag is used when you have a vessel that you are trying to fill and need to vent air. The LM4 or LM3 connector can also be used if you require your BFM® fitting (connector) to breath, often due to pressures. The LM3 breathes more air than the LM4, but could also bleed more product. This will depend on pressure, product, application and conditions.
FM1 breather bags are available in lengths from 100mm (4") to 1 metre (3ft 3").
