Application Area
🏭 Chemical / Spray Painting Workshops
Removal of VOCs and odors from industrial environments.
🔬 Laboratories / Hospitals
Removal of harmful gases and microbial aerosols.
🌀 HVAC Systems
Improving indoor air quality in commercial and public buildings.
Filter Media Materials
We have 3 types of Carbon Activated Media to meet your needs:
Type A
VOC and Ozone, Etc.
Type B
Acidic Gases (SO₂, NO₂, H₂S, HCL, HF, Etc.)
Type C
Alkaline Gases (NH₃, Amines, Etc.)
⚡ Note: Activated carbon is the core of the filter, and its type and quality directly determine the filtration performance.
Main Structure & Working Principle
- Shell: Usually a vertical tank made of carbon steel (with internal anti-corrosion lining) or stainless steel.
- Upper Water/Air Distribution System: Ensures even distribution of fluid or gas across the top cross-section of the filter.
- Activated Carbon Bed: The core component. The activated carbon (often granular) is supported by V-shaped screens, wedge-wire filter tubes, or perforated plates, forming a "V"-shaped cross-section that is narrow at the top and wide at the bottom.
- Lower Water/Air Collection System: Collects the medium that has passed through the filter bed.
- Accessories: Sight glass, manhole, sampling port, pressure gauge, etc.
The Efficiency of V-Type Activated Carbon Filter
The efficiency depends on the carbon content, normally ranging from 2.0 to 4.0, and can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.

Key Operation & Maintenance Points
- 1. Down Flow Operation: Normal filtration direction is top-to-bottom.
- 2. Regular Back Washing: Aims to remove trapped suspended solids and loosen the carbon bed to prevent compaction. Backwash direction is bottom-to-top. Intensity and duration must be controlled to avoid activated carbon loss.
- 3. Monitoring Indicators:
- Pressure Differential: Backwash is required when the inlet-outlet pressure drop increases to a set value (typically 0.05–0.1 MPa).
- Effluent Quality: Indicators like residual chlorine, COD, TOC. Exceeding limits indicates carbon adsorption saturation.
- Activated Carbon Replacement: When adsorption capacity is saturated and cannot be restored by back washing or regeneration, the media must be completely replaced. Replacement cycles for V-type filters are typically longer than for conventional filters.
📋 Summary
The V-Type Activated Carbon Filter, through its unique V-shaped bed design, effectively addresses the pain points of traditional filters: uneven flow distribution, channeling, high pressure drop, and low carbon utilization. It is a highly efficient, energy-saving, and long-lasting activated carbon adsorption device, particularly suitable for medium to large-scale water treatment and air purification systems requiring high treatment effectiveness and operational stability.
When selecting a unit, the filter size, activated carbon type, and specifications must be designed based on the characteristics of the medium being treated (flow rate, pollutant concentration, pH, temperature, etc.), treatment requirements, and available system space.

Frequently Asked Questions (FAQ)
Q What are the main application areas of a V-Type Activated Carbon Filter?
The V-Type Activated Carbon Filter is widely used in chemical and spray painting workshops for VOC and odor removal, in laboratories and hospitals for eliminating harmful gases and microbial aerosols, and in HVAC systems to improve overall indoor air quality.
Q What types of activated carbon media are available, and how do I choose the right one?
There are three types: Type A for VOCs and ozone, Type B for acidic gases (SO₂, NO₂, H₂S, HCl, HF, etc.), and Type C for alkaline gases (NH₃, amines, etc.). The selection should be based on the specific pollutants present in your application environment.
Q What is the efficiency range of the V-Type Activated Carbon Filter?
The filter efficiency is primarily determined by the carbon content and typically ranges from 2.0 to 4.0. The appropriate efficiency level can be selected based on specific treatment requirements and desired economic performance.
Q How often should the activated carbon be replaced or back washed?
Back washing should be performed when the inlet-to-outlet pressure differential rises to 0.05–0.1 MPa. Carbon replacement is necessary when adsorption capacity is fully saturated and cannot be restored by back washing or regeneration. V-type filter replacement cycles are generally longer than those of conventional filters.
Q What are the key advantages of the V-shaped bed design over traditional filters?
The V-shaped bed design ensures more even flow distribution, eliminates channeling, reduces operating pressure drop, and maximizes activated carbon utilization. This results in a more efficient, energy-saving, and longer-lasting filtration device compared to conventional flat-bed filters.
Q What factors should be considered when selecting a V-Type Activated Carbon Filter unit?
Key factors include the flow rate, pollutant type and concentration, pH, temperature of the medium, specific treatment requirements, and the available installation space within the system. Filter size, activated carbon type, and specifications must all be designed accordingly to achieve optimal performance.
