81 Power Vent Battery Box Fans by Zephyr Industries

Why use a Zephyr Industries POWER VENT?

Positive venting of hydrogen and corrosive gases.

Stops back drafting.

Puts the smell outside.

Keeps batteries warmer in cold climates.

Uses very little power.

Excellent results for over seven years.

The POWER VENT was designed for use in remote home power systems.

The concept arose from field experience of systems with enclosed battery

boxes.

Quite often the NEC required venting was found back drafting, thus cooling

the battery bank and lowering its' capacity as well as venting hydrogen gas

into the structure.

The POWER VENT alleviates this condition by keeping a gravity operated

damper closed within the vent pipe except at times when the batteries are

being charged and producing hydrogen gas.

During these times the battery box is force vented with a low power, sparkless

fan which overcomes the damper sending the gas outdoors.

The "fan on" mode is determined by the battery voltage.

When the batteries are "gassing" during charge periods the battery voltage

will read above normal.

A voltage sensitive switch is required in the system to make the on/off

determination.

All TRACE SW model inverters have a programmable auxiliary relay which

can control the POWER VENT.

OUTBACK Inverters have a relay which can operate a POWER VENT

if not used for another function.

Other systems may require the addition of a voltage controlled switch.

The POWER VENT is designed around typical home power systems with

battery banks under 2,200 amp hours and charge rates under 150 dc amperes.

Systems larger than this can produce more hydrogen gas than the expel rate

of the POWER VENT which operates in the 5 to 8 cubic foot per minute range.

Two vents may be used for higher volume.

We suggest the use of a Solar Converters voltage controlled switch Active High

model # VCS 1 - AH to operate the Power Vent.

The VCS 1 - AH will work with the 12, 24 or 48 volt versions.
