Electric Air Curtains
Keep Flies, Dust & Outside Heat From Ever Crossing Your Doorway
An electric air curtain creates an invisible wall of fast-moving air across an open entrance quietly keeping insects, dust and outdoor temperature out while letting people walk through freely. Pest Guard supplies and installs these units for shops, restaurants, warehouses and offices across Trivandrum & Kochi.
What It Does
A Barrier of Air, Guarding Every Open Door
If a fast stream of air has ever brushed over your head as you walked into a shop or office, you’ve experienced an air curtain in action — even if you never noticed the unit mounted above the frame.
Fitted directly above a doorway, it pushes a continuous, high-velocity sheet of air straight down across the opening. That column of air acts like an invisible partition, holding conditioned air inside while stopping flies, dust and outside heat or cold from drifting in — all without ever closing the door.
Air curtains come in a sensor variant and a regular variant. The sensor version only switches on when the door opens, cutting down power use and extending the unit’s working life.
Available Sizes
Four Sizes to Fit Any Doorway
Our air curtains are supplied in four standard lengths so the unit matches your entrance width for full coverage, and each size is offered with or without a door sensor.

Why It Works
What Makes It Effective
- Runs quietly, well under 55 decibels, so it doesn't disturb customers or staff.
- Keeps flies and dust out while helping hold indoor temperature steady.
- Built to run with virtually no maintenance once installed.
How It Works
Two Ways the Unit Can Run
- The sensor variant only blows air the moment someone opens the door — saving power when the entrance is idle.
- The standard variant runs continuously for as long as it's switched on, suited to entrances with constant footfall, like busy kitchens or banquet halls.
