FAQ

1. What is a high negative pressure vacuum dust collector?
A high negative pressure vacuum dust collector is an industrial device that uses strong suction to capture and remove dust, fumes, and fine particles from air. It's ideal for applications requiring high suction power and precise filtration, such as CNC machining, metal grinding, or pharmaceutical production.

 
2. What industries commonly use high vacuum dust collectors?
These systems are widely used in:

CNC machining workshops
Metal and aluminum grinding
Foundries and casting plants
Pharmaceutical and food processing
Electronics manufacturing
Powder coating and sanding lines
 
3. How is it different from a standard dust collector?
High negative pressure systems offer much stronger suction compared to standard baghouse or cartridge-type collectors. They're designed for source capture, long ducting runs, or collecting heavier and finer particles that standard systems may miss.

 
4. What filter options are available?
We offer multiple filtration stages including:

Primary filters (bag or cartridge)
HEPA filters (for fine or hazardous dust)
Optional pre-separators or cyclones
Filter material can be chosen based on dust type, temperature, and humidity.
 
5. Are your dust collectors ATEX or CE certified?
Yes, selected models are CE certified and ATEX compliant, making them suitable for explosive or flammable dust environments in the EU and Southeast Asia markets.

 
6. Can I use this vacuum system for combustible dust (e.g. aluminum, magnesium)?
Yes. We provide explosion-proof models with appropriate grounding, pressure relief vents, and ATEX-rated components for handling combustible dust safely. Please consult our technical team for the correct configuration.

 
7. Is it available in portable or centralized types?
We offer both portable units for flexible workshop use and centralized vacuum systems for large-scale production lines. Custom layouts and multiple suction ports are available upon request.

 
8.  What's your delivery time and export support?
Standard units ship in 10–20 working days. For overseas clients in Southeast Asia, Europe, and the US, we offer export packaging, CE/ATEX documents, and remote installation guidance if needed.
