Heng's Zephyr Roof Vent: SV4112-G4 vs SV4113-G4
Heng's Zephyr is a 12-volt, three-speed reversible roof-vent fan designed for a nominal 14 × 14-inch roof opening. The choice between SV4112-G4 and SV4113-G4 is mainly how the lid and fan are controlled: manual lift versus remote-controlled powered lift with rain sensing.
SV4112-G4 versus SV4113-G4
Both products belong to Heng's Zephyr 12V, three-speed, reversible-airflow family. Their lid-control systems are not the same.
| Manufacturer MPN | Lid operation | Fan control | Rain/remote equipment |
|---|---|---|---|
| SV4112-G4 | Manual lift | Local three-speed controls | No rain-sensor/remote feature listed |
| SV4113-G4 | Powered lid lift | Remote control | Rain-sensor auto-closing |
Electrical reference for the Zephyr family: 12V DC, 18W, 1.6A and 1,200 RPM at high speed, with reversible airflow and high/medium/low settings. These ratings describe the fan system; verify the installation's wiring, protection, roof opening and finish before fitting a replacement.
Before selecting a replacement
- Choose the lid control: SV4112-G4 has manual lid lift and local fan controls; SV4113-G4 adds powered opening with a remote.
- Consider rain sensing: the SV4113-G4 closes when its sensor detects moisture. Do not treat this as a substitute for sound roof seals.
- Check the electrical supply: use a correctly protected 12V DC circuit sized for the fan and the model's supplied controls.
- Plan the garnish: the listings specify a five-inch garnish/collar; confirm the finished roof thickness and any modification needed.
- Allow for ventilation: both models offer reversible air movement and three fan speeds; test lid clearance and operation after installation.
