Smoke Ventilation Air Compressors
Tanair semi-duplex compressor packages for smoke-ventilation, building-services and other specialist compressed-air installations where the compressor and control arrangement must match the engineered system design.
Tanair Semi-Duplex Compressor Range
Choose from piston and rotary-vane semi-duplex packages with 270-litre or 500-litre air receivers and 230V or 415V supply options. These systems are intended for correctly engineered specialist installations where airflow, receiver capacity, electrical supply and control philosophy have been confirmed for the project.
Smoke Ventilation Compressor Packages
Compare the packages by air delivery, receiver size, electrical supply and compressor type. For smoke-ventilation or other safety-related systems, selection should follow the project specification, required control sequence and duty/standby strategy.

How a Semi-Duplex Arrangement Works
A semi-duplex package uses two compressor elements or pumps connected to a shared air receiver. Depending on the system design, suitable controls can alternate the compressors, stage the second unit as demand rises, or provide the operating sequence required by the installation.
Air Demand
Size the package against the required air volume, operating pressure and expected system duty rather than receiver capacity alone.
Electrical Supply
Choose the appropriate 230V or 415V arrangement and confirm starting, isolation and control requirements before installation.
Receiver Capacity
270-litre and 500-litre packages provide different stored-air capacity and installation footprints.
Compressor Type
The range includes piston packages plus a rotary-vane semi-duplex option for suitable specialist applications.
Control Strategy
Alternating, staged or duty/standby operation should be defined by the project design and matched with suitable control equipment.
Service Access
Allow appropriate ventilation, isolation, drainage and clear service access around the compressor package.
Control Panels and System Integration
The compressor package is one part of a smoke-ventilation compressed-air system. Where two compressors need to alternate, stage or provide standby duty, the control arrangement must be selected to suit the project requirements and the electrical supply.

Smoke Ventilation Air Compressor FAQs
What is a semi-duplex air compressor?
A semi-duplex arrangement uses two compressor elements or pumps connected to a shared receiver. The control strategy can alternate or stage them according to the requirements of the installation.
Are 230V and 415V options available?
Yes. The range includes both 230V and 415V packages. Confirm the available electrical supply and the project control requirements before choosing a model.
What receiver sizes are available?
The packages on this page include 270-litre and 500-litre receiver options.
Do I need a dedicated control panel?
Where alternating, staged or duty/standby operation is required, a suitable control arrangement is normally needed. The exact panel, wiring and operating logic must match the system design.
Can Compressed Air Systems UK help with installation and servicing?
Yes. Our team can assist with compressor selection, compressed-air installation and ongoing servicing. For smoke-ventilation and other safety-related systems, the final design, control philosophy and compliance requirements must be confirmed by the responsible competent specialist.
