Vacuum release port

The vacuum release port allows smooth door openings. The door seal is tightened by a negative pressure generated from the temperature difference between inside the chamber and the ambient environment.

*If the port is kept open, the air intake hole get frozen and clogged, and will not allow the door to open smoothly. We recommend to keep it closed unless it is neccessory.
EZlatch EZ latch*

Tightly seals the door, and allows you to open the door with just one hand, with minimum force by allowing the latch to open it on its own using the law of leverage.

*Tested for durability by applying negative pressure – tested over 150,000 times and by drop and impact – tested over 5,000 times
Clip-on grill slide type filter

The condenser filter is situated at the bottom right corner of the front panel to allow easier removal and cleaning.
