DEEP SILENCE 140MM - 1,100RPM
The 140 mm model of the Deep Silence fan series is supplied with a 7-volt adapter cable. At 12 volts the fan rotates at 1,100 revolutions per minute. The Deep Silence 140 mm generates an air flow of 68.5 CFM at a noise level of 14.4 dBA. Using the 7-volt cable reduces the speed to approx. 800 rpm, which generates and air flow of 52,4 CFM at 9.1 dBA.
DEEP SILENCE 140MM - 1,400RPM
The 140 mm models of the Deep Silence fan series are supplied with a 7-volt adapter cable. At 12 volts the fan rotates at 1,400 revolutions per minute. The Deep Silence 140 mm generates an air flow of 76.5 CFM at a noise level of 16.2 dBA. Using the 7-volt cable reduces the speed to approx. 900 rpm, which generates and air flow of 60.1 CFM at 10.5 dBA.
DEEP SILENCE 140MM - 1,800RPM
The 140 mm models of the Deep Silence fan series are supplied with a 7-volt adapter cable. At 12 volts the fan rotates at 1,800 revolutions per minute. The Deep Silence 140 mm generates an air flow of 98,3 CFM at a noise level of 20.8 dBA. Using the 7-volt cable reduces the speed to approx. 1,100 rpm, which generates and air flow of 64.8 CFM at 12.3 dBA.
DEEP SILENCE 140MM - 1,400RPM PWM
The 140 mm model of the Deep Silence fan series is equipped with a 4-pin PWM connector for automatic adjustment of the fan speed. The rotary speed spectrum ranges from 700 to a maximum of 1,400 rounds per minute. The Deep Silence 140 mm PWM 1,400 generates an air flow of up to 76.5 CFM at a noise level of not more than 16.2 dBA. A set of fan shock absorbers as well as a set of fan screws is included.
