Tankrengöringsmaskin BETE HydroWhirl Orbitor 100 för kraftfull och effektiv rengöring av större tankar

SF - Flat fan spray nozzle

FF flat fan nozzle creates coarse atomisation with medium impact spray. The spray angle is extra wide, 105° - 145°.

All 3/8″ FF nozzles in brass can be ordered with 'UL approval'. If you need a flat fan nozzle with 'FM approval', see nozzle AFF.

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.

BETE Performance Spray Engineering

BETE offers test facilities, CFD modelling, and advanced technical support. To ensure high quality and reliable deliveries, BETE's manufacturing is largely based 'in-house' with its own foundry, CNC machining, assembly and quality control.
