Powder-Coated Steel Cleanroom Air Lock

Cleanroom Airlock: Advanced Contamination Control

Terra's modular cleanroom airlock for personnel features a ceiling-mounted HEPA Fan Filter Unit (FFU) that pressurizes the space with micro-filtered air, achieving up to ISO 5 Class 100 conditions. Interlocking doors ensure only one door opens at a time, reducing the risk of cross-contamination.

Smart Fan Filter Unit with EC Motor

WhisperFlow® Smart Fan Filter Units operate quietly and efficiently. They offer adjustable fan speed and pressure balancing settings. Control options include manual adjustment or centralized operation via a smart console.

Durable Powder-Coated Finish

Terra's signature white powder coating provides a sleek, durable barrier that resists corrosion while maintaining a clean, professional appearance. The advanced heat-fused finish exceeds ASTM and ISO standards for durability, protecting against chipping, scratching, fading, and wear.

Motion-Activated Air Shower

Occupancy sensors automatically activate the air shower cycle when the doors are closed, ensuring timely operation.

High-Performance Electronic Components

Terra's electronic components are designed to meet stringent standards required by the defense and semiconductor industries. They deliver exceptional reliability and long-term protection against electrical hazards, damage, and injuries.

Gel-Sealed Room-Side Replaceable Filter

The gel-filled channel on the room-side replaceable HEPA filter creates a secure seal against the knife-edge fan housing. This design allows quick and straightforward filter replacement from within the cleanroom, minimizing downtime and eliminating the need for a full cleanroom shutdown.

Simplified HEPA Filter Maintenance

Room-side replaceable HEPA filters streamline maintenance, allowing filters to be replaced easily using quick-access clips. Replacement is performed inside the airlock, eliminating the need to disassemble the FFU.

Protection Against Contaminants and Pathogens

HEPA and ULPA filters effectively capture many airborne contaminants, including bacteria, viruses (e.g., COVID-19), and mold spores, reducing infection risks for personnel and sensitive biological samples.

BioSafe®: Terra's Standard for Cleanliness

Terra's BioSafe® products are engineered for critical applications. Available as an option for stainless steel air showers, BioSafe® construction features seamless surfaces, rounded corners for easy cleaning, and sterilization-safe materials. BioSafe® products exceed the requirements of cGMP, IEST, ASTM, and ISO 14644-1.

Enhanced Laminar Flow with Uniform Airflow

Non-uniform airflow can cause turbulence, redistributing particles into a clean environment. Terra's WhisperFlow® FFUs incorporate a baffling system and anodized diffuser plates to ensure consistent laminar airflow, minimizing turbulence and efficiently carrying particles away.

Status Indicator Light

Modular cleanrooms include corner-mounted status lights that illuminate when fan/filter units are operational and blink when inactive, providing clear system status at a glance.

Quiet WhisperFlow Operation

Terra's WhisperFlow technology ensures a quieter working environment by reducing noise to levels comparable to a library. At an output of 90 ft/min, WhisperFlow units measure under 50 dB at a distance of one foot, significantly quieter than conventional AC units, which typically measure 70 dB.

Precision Control Panel with Speed Adjustment and Pressure Gauge

Maintaining proper differential pressure is essential for contamination control. Terra's control panel includes a Magnehelic pressure gauge to verify airlock performance and a variable speed dial for precise adjustment of the HEPA FFU, ensuring the desired pressure range is achieved.
