Buy offer Details

Dear sir/madam,
For a project Im working on we need a crossflow fan with the following specifications :
flow : minimum 300 m3/h, preferred 500m3/h
pressure : minimum 25Pa, preferred 35Pa
power supply : 230AC (preferred), or 48V DC
control : PWM or 0-5V control
maximum absolute length : 550mm (incuding motor)
maximum height : 130mm (lower is better)
This fan will be used in outside conditions (moist air), but will be covered from rain. It should not rust when exposed to outside air for multiple years. The purpose of this fan is to provide air for a heat pump evaporator.
Initially, well be requesting samples (2-10 pc), if suitable, first order will be 150pc, next order will be around 1000pc (in batches of 200pc/month)
Can you offer me a suitable product? Id love to hear from you.
Best regards,
Marijn Blom
