NOTE
All 1830 Series ventilators are for a 4" (101.6mm) thick wall. When other length is required, specify exact wall thickness. Kason will convert
your individual requirement into our part number.

NOTES:
(1) The table above should be used as a general guideline only. Kason does not guarantee these numbers, as many factors beyond those assumed can affect the amount of ventilation required in a refrigerated space. Some of these factors include, but are not limited to: the number
of doors in the enclosure, air-tightness of the enclosure, refrigeration load (how quickly the temperature drops), strength of panel construction,
etc.
(2) Vent quantities are calculated based on actual measured flow rates at an assumed allowable pressure differential for given temperature
change rate: 1825 = 13 ft3/min @ .6in H
sure.
(3) For box temperature less than -20F and/or when humid conditions exist outside box, add one 1830 for each 2000 cf above 6000 - or use 1832LT.
(4) Model 1832LT is recommended over the 1832 for box temperatures between -20F and -40F. Use model 1845 for boxes this size and
larger if box temperature is -20F or greater.
(5) Minimum use temperatures: 1825 -20F, 1830 & 1832 -30F, 1832LT -40F.
(6) Opening pressures: 1825 opens at the lowest pressure (0.1 in. H
in. H
O).
