China Factory Paint Mist Collector Filter - Eco-Friendly Cardboard Frame, 93% Efficiency, EN 779 G4 Standard Suppliers
🏭 Application Area
✅
It is widely used in dry painting spray booths, dry painting systems for automobile, furniture, mechanical parts, and complex assemblies — paint mist filtration or dust collection filtration systems in workshops.
🧪 Filter Media Materials
The filter media is the core component for capturing paint over spray, typically made of fluffy, porous materials with high dust-holding capacity. The main types are as follows:
🔶
Glass Fiber
- Characteristics: The most commonly used, classic paint filtration material.
- Advantages: High fire resistance rating (usually Class A non-combustible), moisture-resistant, chemically corrosion-resistant, high dust-holding capacity, stable efficiency.
- Form: Usually a fluffy, white, cotton-like structure that effectively intercepts and absorbs wet paint particles.
🔷
Synthetic Fiber
- Characteristics: Such as polyester fiber (PET), etc.
- Advantages: Good toughness, potentially higher filtration efficiency, more environmentally friendly (some products are recyclable).
- Disadvantages: Generally inferior fire resistance compared to glass fiber (usually flame-retardant grade, not non-combustible).
🔵
Composite Fiber
- Characteristics: A blend of fibers of different thicknesses and materials to balance filtration efficiency, resistance, and dust-holding capacity.
📋 Summary and Key Selection Points
| Component | Main Material | Key Characteristics |
|---|---|---|
| Frame | Special Kraft Paper / Cardboard | High strength, moisture-resistant, flame-retardant (treated), lightweight, low cost |
| Filter Media | Glass Fiber | Most common, fire-resistant (Class A non-combustible), moisture-resistant, high dust-holding capacity |
| Filter Media | Synthetic Fiber (e.g., PET) | High toughness, high efficiency, more environmentally friendly (note fire rating) |
When selecting, you need to focus on the following points:
-
🔥
Fire Resistance Rating In environments like spray booths where sparks are a risk, Class A non-combustible glass fiber filter media is the preferred choice for the highest safety.
-
🎯
Filtration Efficiency Choose filter media with different densities and structures based on the type of paint you are spraying (water-based/oil-based) and the required paint over spray capture efficiency.
-
📦
Dust-Holding Capacity A higher dust-holding capacity means a longer service life for the filter and lower replacement frequency, making it more economical in the long run.
-
💧
Moisture Resistance Especially in areas with high humidity or when using water-based paints, moisture resistance is crucial to prevent premature filter failure.
⚡ The Efficiency of Paint Mist Collector Filter
The efficiency of currently available are:
📊 93% Filtration Efficiency
They can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.
🔄 Service Life of Filters
As dust accumulates on the filter media, the resistance increases. When the resistance reaches an unreasonable level, the filter must be discarded. Sometimes, excessive resistance can cause previously captured dust to become dislodged and re-enter the airflow; when this risk arises, the filter should also be replaced.
⚠️
Important Note: The resistance of a filter increases with higher airflow rates. By increasing the surface area of the filter media, the relative velocity of air passing through the filter can be reduced, thereby decreasing the resistance.

❓ Frequently Asked Questions (FAQ)
Q
What is a paint mist collector filter used for?
Paint mist collector filters are used in dry painting spray booths and systems for automobiles, furniture, mechanical parts, and complex assemblies. They capture paint over spray and airborne dust particles to maintain clean air in the workshop and protect workers and equipment.
Q
What filter media material is best for spray booth applications?
Glass fiber is the most recommended material for spray booth applications due to its Class A non-combustible fire resistance rating, excellent moisture resistance, chemical corrosion resistance, and high dust-holding capacity. In environments where sparks are a risk, it is the safest and most reliable choice.
Q
What filtration efficiency do paint mist collector filters offer?
Currently available paint mist collector filters achieve a filtration efficiency of up to 93%. The appropriate efficiency level can be selected based on specific application requirements. The rational selection of filter efficiency and face velocity is essential to achieving comprehensive economic benefits.
Q
How do I know when it's time to replace the paint mist collector filter?
The filter should be replaced when the airflow resistance increases to an unreasonable level due to accumulated dust and paint particles. Additionally, if excessive resistance causes previously captured dust to become dislodged and re-enter the airflow, the filter must be replaced immediately to maintain air quality and system performance.
Q
Can the filter dimensions be customized to fit different spray booth sizes?
Yes, custom sizing is supported to accommodate different spray booth configurations and customer requirements. Please refer to the specification sheet for standard dimensions, and contact the supplier directly for custom size orders. Initial resistance tolerance is ±10%.
Q
Is moisture resistance important when choosing a paint mist filter?
Yes, moisture resistance is a critical selection factor, especially in high-humidity environments or when working with water-based paints. A filter without adequate moisture resistance may deteriorate prematurely, leading to reduced filtration performance, increased maintenance costs, and potential safety risks in the spray booth.
