Overview
A fan filter pass through hatch is an essential component used in cleanroom environments to enable the safe transfer of materials between areas with different cleanliness standards.
Facilities can maintain high standards of cleanliness and contamination control by using fan filter pass-through hatches, which allow for the safe and efficient transfer of materials between cleanroom areas.
Created to deliver prompt air changes and swift clean-up/recovery periods, reducing the waiting period when transferring products between different classification rooms within cleanroom facilities.
This fan filter cleanroom pass through from PBSC has been designed to operate without any connection to the facility’s HVAC system, utilizing the air from the adjacent rooms, and decreasing the costs of HVAC systems.
The hatch is manufactured in 304 or 316 grade stainless steel, with minimal visible fixings and recesses, enabling easy cleaning, and the completely frameless glass door leaf provides maximum visibility and natural light.
The trustworthy interlock mechanism is mounted between the two skins of the hatch to reduce the risk of tamper and is available as an electro-mechanical system to supply timed interlocks for air purge cycles, UV light cycles, etc. This assists in the lessening of cross contamination, and pressure loss whilst passing products between lower and high classification areas., thus ensuring a safe and secure operation.
The advanced configuration is robust and delivers effortless cleaning and maintenance.
Having a built-in recirculation fan and HEPA filter system with an adjustable fan speed controller allows for between 20-300 air changes per hour, depending on the size of the hatch.
The HEPA (High-Efficiency Particulate Air) filter transfer hatch from PBSC can filter small particles, removing up to 99.9% of the particles in the air stream, with rapid particle reduction to meet or surpass the higher grade room requirements with minimal duration.
Numerous UV lights can be included to decrease bioburden. The number of UV lights and length of a cycle is user modifiable. The system observes the life of the UV light with a counter to allow the opportunity to change bulbs at the correct time.
The system is available with either 120V/60Hz or 230/50Hz power supply.
Advantages:
- Maintained Air Quality: By ensuring a clean environment inside the hatch, these units help maintain air quality and reduce the transfer of particulate matter.
- Efficient Workflow: Streamlines the process of transferring materials between cleanrooms, improving overall workflow efficiency and reducing the need for additional decontamination steps.
- Pressure Regulation: Helps maintain proper pressure differentials between cleanroom areas, which is crucial for contamination control.
- User-Friendly Design: Easy-to-clean surfaces and robust construction make these hatches practical and reliable for everyday use in demanding environments.
- Compliance and Safety: Meets industry standards for cleanroom operations, ensuring regulatory compliance and maintaining a safe working environment.
- Enhanced Contamination Control: The continuous airflow provided by the FFU and HEPA filtration minimizes the risk of contamination during material transfer.
PBSC’s hatches are available with a range of features and options including:
Innovation. Design. Quality.
The FFU uses HEPA filters to remove particulate contaminants from the air, maintaining the required cleanliness levels within the hatch.
Each hatch is equipped with a fan filter unit (FFU) that provides continuous airflow, ensuring a clean environment inside the hatch during the transfer process.
The Fan Filter hatch has a built-in recirculation fan and HEPA filter system with an adjustable fan speed controller to allow for between 20-300 air changes per hour, subject to the size of the hatch.
The hatch features PBSC’s dependable interlock system that ensures only one door can be opened at a time, preventing cross-contamination between rooms.
Manufactured from robust, smooth, and non-porous materials such as 304 or 316 stainless steel, with minimal visible fixings or recesses.
A completely frameless glass door leaf provides maximum visibility and natural light into and through the hatch.
Options for internal support shelves in glass or stainless steel, and compatibility with different types of wall constructions.
Available in various sizes and configurations, including single or double door options and right-angle designs, to suit specific cleanroom requirements.
Following on-site installation, PBSC offers a Planned Preventative Maintenance and Servicing Plan with an extensive after-sales support service, including planned preventative maintenance programs, servicing, and spare parts.
