Technical Specifications and Performance Analysis of the Turlach Post 171 Stack Filter
Primary Conclusion: The Turlach Post 171 is a commercial stack filter unit designed for industrial ventilation systems. Its primary function is to remove particulate matter, such as dust, grease, and acid mist, from exhaust gases before they are released into the atmosphere. The unit is specified with a high airflow capacity of 7,893 cubic metres per hour (m³/h), a filtration rating of 49 micrometres (um), and a service interval of 2,441 hours.
1. Overview and Function
The Turlach Post 171 is a mixing-height stack filter, also known as a bag filter or cyclone filter. It is mounted downstream from an air source or ventilator to capture and filter pollutants that have been released into the atmosphere.
Mechanism of Action: The unit operates on a multi-stage principle:
Inlet: Pollutant-laden air is drawn into the unit.
First Stage (Pre-Combustion): Air is forced to move rapidly through a primary chamber. This high-speed flow causes larger particles (like dust and grease) to collide and stick to filter media, while smaller particles pass through.
Secondary Filtration (Cyclone Action): The air then enters a secondary chamber where it is forced into a spiral motion by centrifugal force. This motion enhances the contact between the air and the filter media, ensuring a higher concentration of captured particles. This is the "stack" effect mentioned in the specification.
Exhaust: Clean, particulate-free air is collected by the unit and expelled out the exhaust duct.
This design is particularly effective for capturing a wide range of industrial pollutants, including:
* Particulate Matter (PM)
* Grease and oil mist
* Acid mist
* Dust and grit
2. Key Technical Specifications
The following table details the specific technical parameters of the Turlach Post 171.
| Specification | Unit of Measurement | Value |
| ------------------------------ | -------------------------- | --------------------- |
| Airflow (Q) | cubic metres per hour (m³/h) | 7,893 m³/h |
| Filtration Rating (UM) | micrometres (um) | 49 um |
| Pressure Drop (ΔP) | pascals (Pa) | 240 Pa |
| Service Interval (H) | hours | 2,441 h |
| Unit Price (USD) | dollars | $9,034.27 |
| Filter Medium | pleated fibre | N/A |
Note: The service interval is the average time between filter changes required to maintain effective performance.
3. Performance and Efficiency Analysis
The performance of the Turlach Post 171 can be analyzed against standard industry benchmarks.
High Airflow Handling: The 7,893 m³/h airflow rate is crucial for applications requiring significant ventilation, such as large manufacturing facilities or open-pit mines.
Small Particle Filtration: The 49 um filtration rating is a key performance indicator. It signifies the smallest particle size that the filter can effectively capture. For comparison, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends that a stack filter's rating should be at least 2.5 times the size of the largest particle being removed to ensure complete capture.
Pressure Drop: A pressure drop of 240 Pa indicates the resistance the filter medium creates to airflow. This value must be managed by the system to ensure efficient operation and prevent damage to the fan unit.

Turlach Post 171 Stack Filter: Technical Specifications and Performance Analysis
Primary Conclusion: The Turlach Post 171 is a high-capacity industrial stack filter with a primary airflow of 7,893 m³/h, a 49-micrometre filtration rating, and a service interval of 2,441 hours. It is designed to capture particulate matter, grease, and acid mist from exhaust gases.
1. Overview and Function
The Turlach Post 171 is a mixing-height stack filter unit used in industrial ventilation systems to remove harmful pollutants from the air before it is released into the atmosphere. Its operation relies on a multi-stage process to achieve high-efficiency particle removal.
Mechanism of Action: The unit employs a two-stage filtration process:
Inlet: Pollutant-laden air is drawn into the unit.
First Stage (Pre-Combustion): Air is forced to move rapidly through a primary chamber. Larger particles are collected via inertial collection, while smaller particles pass through to the next stage.
Secondary Filtration (Cyclone Action): The air is then forced into a spiral motion by centrifugal force. This high-speed, circular motion enhances particle contact with the filter media, ensuring a higher concentration of captured particles. This is the "stack" effect.
This design is effective for capturing a wide range of industrial pollutants, including Particulate Matter (PM), grease mist, acid mist, and dust.
