SAM - Air atomising spray nozzle

SAM is an air atomising nozzle that allows you to control/set the droplet size without affecting liquid flow rates. Higher atomising air pressure yields finer drop size.

SAM air atomising nozzle is suitable for all liquids, including viscous media above 200 cP.

SAM is an air atomising nozzle that allows you to control/adjust the droplet size without affecting the liquid flow. The higher the air pressure, the finer the droplets. The SAM nozzle is suitable for all types of liquids, even viscous liquids above 200 cP. SAM is manufactured by BETE Spray Technology.
Illustration of how the spray is created by an air atomising nozzle with external mixing. Air and liquid leave the nozzle through two separate orifice holes. Air and liquid flow can be controlled independently of each other, making it possible to set a specific liquid flow at a given air flow. Suitable for all types of liquids, even above 200 cP.

Design features

  • Liquid flow rates are independent of air. Higher atomising air pressure yields finer drop size.
  • Separate atomising and fan air lines provide variable coverage
  • Pneumatically controlled shut-off and built-in clean-out
  • Liquid flow rates are independent of air
  • Precise metering of the liquid flow rate
  • Suitable for all liquids, including viscous media above 200 cP
  • SAM can be used together with BETEs FlexFlow™ Spray Control System, a plug-and-play system for flexible automation and high precision

Choose the right spray nozzle for an optimised spray process

Each type of nozzle has a specific flow rate, spray pattern and droplet size. To optimise the spray process, it is important to understand how different parameters affect the choice of spray nozzle and type of solution.

The Knowledge base contains information about spray pattern, droplet size, flow rate/pressure, spray coverage, materials, etc. The 'Materials' section of the Knowledge base lists the most commonly requested materials and maximum temperature of the material.

Our main supplier is BETE, a leading manufacturer of spray nozzles and spray systems with more than 70 years of experience in spray processes and a product range including over 20,000 components.

BETE's spray technology is used worldwide to optimise processes in many different industries, including the energy sector, chemical and petrochemical industry, food industry and offshore.

Some of BETE's certifications include ISO 9001:2015, ATEX and FM Approval.
