Ranveth dust collection bags are multi-layer filter bags built around a composite PP meltblown medium and a moulded plastic cover plate. They capture fine dust, mite allergens and pollen from the exhaust air of robot vacuum auto-empty docks, handheld vacuums and commercial vacuum bins. The bags are made for OEM and ODM programmes that need a sealed, low-resistance bag matched to a specific dock or vacuum model. Ranveth manufactures them in Zhongshan, Guangdong, China, with media and layer choices backed by its CNAS-accredited laboratory.
The performance of a dust bag comes from how its layers are paired, not from any single material. Ranveth builds the bag from a multi-layer composite of polypropylene nonwoven and meltblown PP, with an optional antibacterial filter cotton layer. The nonwoven layers give the bag its strength and pleat stability under vacuum pressure, while the meltblown layer does the fine particle capture. Because the meltblown web is protected between nonwoven layers, it resists abrasion from coarse debris and keeps its structure through repeated filling cycles.
This pairing is tuned for three outcomes. First, filtration: the composite intercepts PM2.5-level dust, dust mites, pollen and hair, so exhaust air is not a source of secondary contamination. Second, airflow: a high-porosity breathable design keeps resistance low, so the motor does not lose suction as the bag fills. Third, capacity: the layer stack holds a high dust load before the pressure drop rises, which extends service life. When a customer needs odour control, we can add an activated carbon layer without changing the outer dimensions.

| Company certification systems | 50,000 m² modern clean production plant and a CNAS-accredited testing centre. Company operates under ISO 9001, ISO 14001 and IATF 16949 quality management systems |
In all three uses the bag is a consumable that protects the motor and the indoor environment. The plastic cover plate is the interface between the bag and the device, so its dimensions and latch geometry are developed from the customer's model or drawing.
To quote a custom bag, we need the device or vehicle model, a size drawing or physical sample of the dock or bin opening, and the expected airflow or water flow of the system. Please also share the operating conditions, such as typical dust type, humidity and temperature range, and the order quantity. With these inputs our engineers select the media grade, layer order and collar design, then confirm the sample before production.
Media decisions here are test-backed. Ranveth's in-house laboratory holds CNAS accreditation (China National Accreditation Service for Conformity Assessment) and issues reports for filtration efficiency, dust holding capacity and airflow resistance. That means the layer pairing on your bag can be verified against the performance you specify.
Production runs in a 50,000 m² plant, including six cleanrooms totalling 20,000 m², which limits dust and fibre cross-contamination during bag assembly. The company has held IATF 16949 since 2024 and operates ISO 9001, ISO 14001 and ISO 45001 systems. Products meet REACH and RoHS requirements, and compliance documents are available. With more than 20 years of filter development and export experience to Europe, the US, Japan and Korea, Ranveth supports OEM/ODM work covering size, structure, media grade, collar material, logo and packaging, and has developed over 1,000 filter solutions.

The bag uses a multi-layer composite of polypropylene nonwoven and meltblown PP, with an optional antibacterial filter cotton layer. The nonwoven layers provide strength, while the meltblown layer captures fine particles. An activated carbon layer can be added for odour control.
The composite structure intercepts PM2.5-level dust, dust mites, pollen and hair, preventing secondary exhaust contamination. Efficiency is verified at Ranveth's CNAS-accredited laboratory, which issues test reports for each design. Exact figures depend on the media grade selected for your application.
Yes. Bags are 100% customised to device dimensions, with cardboard or injection-moulded plastic collars, sliding automatic-seal options and activated-carbon versions. We develop the collar from your model, drawing or sample. Logo and packaging customisation are also available.
Send your device model, size or drawing, expected airflow or water flow, operating conditions and order quantity through our contact page. Our engineers will recommend a media grade and provide a sample plan and quotation. Samples are confirmed before production.
MOQ depends on the specification and customisation level. Standard configurations have lower thresholds, while fully custom collars and media grades may require a higher quantity. Share your requirements and we will confirm the MOQ in the quote.
Lead time varies with order quantity and customisation. Standard bags typically ship in 7–15 days, while custom tooling and new collar development usually take 30–45 days after order confirmation. We will confirm the schedule when quoting.
Replacement depends on dust load and vacuum usage. The high dust holding capacity and low resistance design allow longer intervals between changes. We recommend replacing the bag when suction noticeably drops or when the bag is about three-quarters full.
Yes. The plastic cover plate features a sliding handle that seals the bag opening before removal, so dust stays inside. This automatic-seal design keeps the process clean and avoids secondary contamination.
