HORIZONTAL SIDEWALL VENTING

For applications where vertical venting is not possible, the only approved method of horizontal venting is the use of an auxiliary power vent. Approved power venters are Fields Controls Model SWG-4Y or Tjernlund Model GPAK-JT. Fol- low all application and installation details provided by the manufacturer of the power vent. This unit may be horizontally vented using 4” (10.2 cm) diameter pipe with a minimum length of 4.5 feet (1.37 m) and a maximum length of 34.5 feet (10.82 m) with up to 4 elbows.

FILTER PERFORMANCE

The airflow capacity data published in the “Blower Perfor- mance” table listed above represents blower performance WITHOUT filters. To determine the approximate blower per- formance of the system, apply the filter drop value for the fil- ter being used or select an appropriate value from the “Filter Performance” table shown below.

NOTE: The filter pressure drop values in the “Filter Perfor- mance” table shown below are typical values for the type of filter listed and should only be used as a guideline. Actual pressure drop ratings for each filter type vary between filter manufacturer.

NOTES:

1. Air velocity through throwaway type filters may not exceed 300 feet per minute. All velocities over this require the use of high velocity filters.

2. Air flows above 1800 CFM require either return from two sides or one side plus bottom.
