Axial fan YWF4Е-300S

Axial fans Tidar

Axial fans General purpose series YWF, production company Tidar, Ltd (China) are designed to move air or other non-explosive, nagresign gas mixtures with temperatures ranging from -40 to +600C, not containing sticky substances and fibrous materials the concentration of dust and other solid impurities not more than 10mg/m3.
In the setup of fans RMS value of vibration velocity from external sources of vibration should not exceed 2 mm/s
