Sealing Air Busch

BML Seal air busch are the right solution where 100% positive isolation against the process gas is required.

Our seal air design is based on pressurising the interspace between the damper blade seals at a pressure which is consistently higher than the upstream process. Our flexible special alloy seals provide durability even at high temperatures, so are perfect for heavy duty applications.

BML Sealing Air Busch can be manufactured in Carbon Steel or Stainless steel, however for special applications we can utilise any material to suit your requirements such as 800HT, 310S, Alloy 31, Alloy 59…

Butterfly, Multilouvre, Guillotinesand Diverters can also be supplied with sealing air for 100% positive isolation.

BML can design and supply the full seal air system, such as ducting, heaters, non-return busch, fans, mounting arrangement. We evaluate your project specific process data so we can calculate and determine the optimum fan size, power consumption and seal air control method to suit your application. Fans and controls can be provided with appropriate certification for hazardous area applications such as ATEX.
