Airlock Breakdown

More Information

Non-Pressurized Airlocks
These airlocks are ready-to-install systems that allow personnel to conveniently enter and exit controlled environments with minimal airflow disturbance. The airlock provides a neutral air zone that minimizes air turbulence and other disturbances when moving between cleanrooms or other controlled environments.
  • Each cleanroom airlock is shipped fully assembled; simply connect the power cable to begin operation
  • Interlock function prevents both doors from being opened at the same time
  • Emergency release button located inside of the airlock immediately unlocks both doors in the event of an emergency (requires manual reset)
  • A bypass key-switch disables the interlock during maintenance or cleaning (the key can be removed to prevent tampering)
  • White powder-coated steel finish (304 stainless steel finish available at additional cost)
Pressurized Airlocks
These Airlocks are equipped with a 2' x 4' low-energy EC Fan/Filter Unit, which pressurizes the airlock with HEPA-filtered air. A pressurized airlock prevents cross-contamination between two critically controlled environments, such as ISO-classified cleanrooms with varying pressure levels. Any potentially contaminated air that enters the airlock is quickly purged through the vents before personnel can proceed to the next room.

These types of airlocks provide an additional layer of security that is particularly useful for fields like biotechnology, where certain operations must be isolated from the rest of the facility to avoid compromising sensitive research materials. A pressurized airlock provides a simple solution for providing the environmental controls necessary to meet most GMP or GLP standards. For more stringent requirements, see Terra's Smart Cleanroom Airlocks.
  • Fan/Filter Unit (FFU) with EC motor and room-side replaceable HEPA filter that purges the airlock with micro-filtered air and pressurizes the space to minimize particle influx
  • Vents positioned near the floor allow air to escape while maintaining uniform airflow
  • A continuously variable speed dial for precise control of blower speed and pressure balancing
  • FFU pressure sensor that indicates the need for HEPA filter replacement
Smart Airlocks
The Smart Airlock system upgrade allows for automation of the various airlock functions as well as the addition of a wide range of security features. The Smart system uses a modular control board that allows you to mix-and-match different electronic options to customize the airlock for your application.

The Smart Airlock base system adds the following:
  • LED status bar above the door that glows green when the airlock is ready for use (and red when the interlock has been activated)
  • Audible alarms that warn personnel when an airlock door has been left ajar, rendering the airlock inoperable for personnel on the other side
Optional Smart modules (only available on Smart Airlocks):
  • Automatic Doors that are activated by a wave your hand using a motion-detecting panel in place of push-buttons
  • Integrated Timers that unlock/auto-open doors after a preset waiting period, allowing adequate time for the air to stabilize
  • Automated FFU Controls that monitor and maintain differential pressure
  • Security Modules that require a passcode or biometric measurements (such as an iris scan) before granting access
  • Security Cameras and Access Logs that can provide additional internal controls for compliance purposes
  • Motion Sensors that can be used to activate other components, such as lights and air showers
  • Touchscreen Control Panels that simplify programming and can relay data from remote sensors
Oversized, High-Speed Airlock
An oversized airlock allows personnel to accompany large carts or equipment as it is transferred between controlled environments. These interlocked doors are specially designed to allow a single person to operate the airlock from start to finish, eliminating the need for a second person on the receiving end. This results in significant improvements in efficiency, especially when combined with the various automated accessories that allow for hands-free operation.

The UV-resistant vinyl doors and flexible PVC windows are made of cleanroom-appropriate materials, meaning they are non-shedding and easy to clean. The sealed motor provides a door travel speed of approximately 28 inches per second and can be equipped to provide up to 70 cycles per hour.

Doors are soft and lightweight, with further protection provided by the photoelectric sensors that detect objects in the door’s path. In the event of a total power loss, both doors will immediately roll up to provide a safe exit.

Cleanroom Airlock Protects Against Cross-Contamination

Terra’s modular cleanroom airlock for personnel features a ceiling mounted HEPA FFU that pressurizes the enclosure with micro-filtered air to achieve up to ISO 5 Class 100 conditions. The interlocking doors prevent both doors from opening at the same time to further minimize cross-contamination.

Smart Fan Filter Unit with EC Motor

Smart WhisperFlow® Fan Filter Units are quiet, energy-efficient and easily adjustable, either manually or via automatic smart console, for centralized fan speed control and cleanroom pressure balancing.

Clean and Durable Powder Coat Finish

Terra’s signature white powder coat finish provides a high quality, durable barrier to protect against corrosion, plus a clean and attractive aesthetic. The advanced heat-fused formulation exceeds ASTM and ISO paint standards to resist chipping, scratching, fading, and wearing.

Motion Sensors

Occupancy sensor activates air shower when doors are closed

Highest Standards For Electronic Components

Terra’s electronic components are designed and built to the highest standards required by defense and semiconductor industries for long-term reliability and protection against damage, injuries, and electrical hazards.

Gel-Filled Channel on Room-Side Replaceable Filter

Gel-filled channel on room-side replaceable filter forms a tight seal against knife edge on fan housing, allowing fast, simple filter replacement from inside the cleanroom without the need for costly cleanroom shut-down.

Room-Side Replaceable HEPA Filter Simplifies Maintenance

Room-side-replaceable HEPA filters drastically simplify filter replacement to keep your cleanroom operations running smoothly. The ceiling mounted FFU features easy-open clips allowing for filter replacement from within the airlock, without dismantling the entire FFU.

Protect Against Contaminants and Pathogens

HEPA and ULPA filters help capture many bacteria, viruses (COVID-19), and mold spores that contribute to a host of infections for both humans and plant/animal tissue cultures

Airflow Uniformity Improves Laminar Flow

Non-uniform air speeds produce turbulence that can recirculate particles into the air stream. Unique WhisperFlow® FFU baffling system and anodized diffuser plate promotes uniform laminar airflow to minimize turbulence and effectively carry away contaminating particles.

Operation Status Indicator Light

Modular Cleanrooms include a status indicator light in each corner, which glows when fan/filter units are operating and blinks when they are inactive.

WhisperFlow Quiet Operation Reduces Distracting Background Noise

Exposure to loud noises can lower the ability to focus on work and listen selectively, which may also lead to safety issues. Typical AC units can be annoyingly loud, measuring in the range of 70 dB (comparable to a vacuum cleaner). Terra’s WhisperFlow design produces far lower noise levels for a quiet environment comparable to a library. At 90 ft/min output, units measure under 50 dB from only 1 ft away (roughly 75% quieter than 70dB).

Continuous Product Improvement

At Terra, we strive to develop and produce the highest quality products for our customers to improve health, safety, performance, and yields. Our product quality is enabled by high-grade manufacturing equipment and processes, 45 years of engineering and application expertise, and our commitment to continuously improve.

Control Panel with Variable Speed Control and Pressure Gauge

Maintaining the right amount of differential pressure is essential to preventing cross-contamination. The Magnehelic differential pressure gauge helps verify the airlock is working as intended. The infinitely variable speed dial beneath the gauge allows precision speed adjustment of the HEPA FFU to achieve the desired pressure range.
