Install a PVC rapid rolling doors interlocking with air curtains

Recently, KENVO DOOR finished a project of PVC rapid rolling doors in SAUDI ARABIA. This client is a famous food factory producing fast foods in whole Saudi Arabia. They have very strict requirement to keep clean and tidy inside their factory and also warehouse.

They choose KENVO standard model PVC rapid rolling up doors for all interior door openings. Even though the PVC rapid doors are very fast and only take seconds to open and close, clients still want to make it further, to avoid dust and air during door open time. So we add air curtains above the door head, and interlock the air curtain with door. Once door is opening, the air curtains will automatically start to run and create a air wall to prevent dust. After door is closed, the air curtain will stop working immediately.
