Air Curtain Guide: Door Air Barriers for Shops, Restaurants and Clinics, Width and Airflow, Unheated and Heated Types, Mounting Height, Noise, Power Use, Indicative Rates by Size, Fitting and Maintenance in Pakistan
An air curtain is a fan unit above a door that blows a sheet of air across the opening to keep out flies, dust, heat and some cold air while the door stays open. It suits shops, restaurants, clinics and kitchens. Prices run from about PKR 6,000 to PKR 60,000 depending on width and power. This page covers how it works, width and airflow, unheated and heated types, mounting height, noise, power use, rates, fitting and maintenance. For related pages see window nets, PVC and plastic curtains and door curtains.
How an air curtain works
A fan pushes air through a narrow slot to form a fast sheet that slopes slightly outwards, creating a barrier. It reduces flies, dust and warm outside air entering, and helps keep cooled air in air-conditioned shops. It is not a seal and works best with a door left open for traffic.

Prices move with brand, model, size and stock. Use these ranges to judge a quote, then compare the exact model and what is included.
Width and airflow
Choose a unit as wide as the door or wider, and check air speed at the floor, since a weak fan fails in windy or tall doorways. Taller doors and busy shops need higher airflow.
Unheated and heated types
Unheated units suit shops and kitchens in warm climates, and heated units help keep winter cold out. Heated types draw far more power, so check your supply.
Mounting height and position
Mount inside the doorway above the opening, usually 2.4 to 3 metres high, with the airflow pointing slightly outward. Poor positioning wastes power.
Noise and power use
Fans make noise, so choose quieter models for clinics and cafes, and check wattage, usually 50 to 150 W for unheated models. Use a switch linked to the door where possible.
Fitting and maintenance
Fix the unit to a strong wall and use proper wiring and a switch. Clean grilles and filters regularly to avoid dust build-up. Fitting should be done by a trained fixer, and the window frame, wall and fixing points checked for strength first.
Before you decide
Match width and airflow to the door, choose a quiet model and mount it correctly. Measure the window or opening twice, order a small sample or a single panel first if the job is large, compare at least two quotes on the same specification of fabric, hardware and fitting, and keep the invoice and warranty card. Confirm delivery and fitting dates in writing, check the finished work in daylight and at night, and ask the supplier what happens if the colour or size differs from the sample. Prices change with fabric costs and stock, so confirm the current figure before you decide.
