BM Nozzles Nozzles for Vehicle Fire Protection

 Always demand ROLLED LIP pat. core retention for guaranteed spray dispersion 



BM Blow-Off Series

Spray Nozzle Engineering designs & manufactures a full range of speciality vehicle fire protection nozzles and protective dust caps. This now includes the BM spray nozzle range with ‘NEW’ Patented Rolled Lip reducing internal vane dislodging from the nozzle body during handling and installation or due to thermal expansion. This technology coupled with the Patented BM14 protective dust caps with retention lanyards utilise an internal O-ring that retains itself on a standard non-modified BM Series nozzle. Older style nozzle systems have an O-ring groove machined on the nozzle body; adding cost to the standard nozzle systems.

BM Series nozzles produce uniform distribution of small to medium sized droplets in both standard and wide angle solid cone spray patterns and along with the patented BM14 protective dust caps make the BM Seriesthe first choice for vehicle engine bay foam fire protection applications in industries such as mining, farming and forestry or in any application required a blow-off protective cap.

BM Foil Series

Because the BM Foil does not use Rubber or Silicone seals and O-rings, it is perfect for applications where an All-Metal system is required over traditional non metal retention system; for example in high heat and dust susceptible environments found in Mining, O Road vehicles and machines.

The BM range is manufactured to batch numbering standards, and is available in both full brass construction, full stainless construction or a combination of the two for improved corrosion resistance. With three common sizes and two spray angles, the range can also be customised for individual applications. BM-Foil Series nozzles produce uniform distribution of small to medium sized droplets in both standard and wide angle solid cone spray patterns; make the BM-Foil Series the first choice for vehicle engine bay foam re protection applications in industries such as mining and farming.
