SENOTAY INDUSTRIAL DUST COLLECTOR PRODUCTION — BOTOU, HEBEI, CHINA
Senotay manufactures the full range of industrial dust removal equipment — from Pulse Jet Bag Filters and Electrostatic Precipitators to Cyclone Collectors, Wet Scrubbers, Cartridge Collectors, and VOC Purifiers — entirely within our own production facility in Botou, China. Every unit is custom-engineered, in-house fabricated, and pre-shipment tested before it leaves our factory.
PRODUCTION CREDENTIALS
15+ Years Manufacturing Experience | 99.9% Filtration Efficiency Achievable | 30+ Industries & Applications Served | Full In-House Design to Delivery |
OUR MANUFACTURING APPROACH
Dust collection equipment ranges enormously in quality — from lightweight, low-grade units that meet specification on paper but fail quickly in service, to properly engineered, robustly manufactured systems that operate reliably for 15–20 years with routine maintenance. The difference lies in how the equipment is designed, what materials are used, how it is welded and coated, and whether it is actually tested before it ships.
At Senotay, every dust collector we produce goes through a 10-stage production process that begins with engineering analysis of your specific process conditions and ends with a documented pre-shipment test record. We do not produce generic catalogue units. Every order is sized for the actual gas volume, temperature, dust type, and emission limit of the application it is destined for.
This page describes our full dust collector production range, the technical specifications we work to, the production process we follow, the industries we serve, and the reasons why customers across more than 30 industries on multiple continents choose Senotay equipment for their dust removal projects.

FLAGSHIP PRODUCT
The Pulse Jet Bag Filter is our most widely produced dust collector and the technology of choice for the majority of industrial dust removal applications. Its combination of very high filtration efficiency, continuous on-line cleaning, broad operating temperature range, and compatibility with almost any dry industrial dust makes it the standard solution for applications from cement and power generation to food processing and pharmaceuticals.
Every Pulse Bag Filter we produce is divided into three main structural sections, each fabricated and assembled in our dedicated production workshops:
• Upper clean-air plenum — houses the compressed air reservoir, pulse pipe manifolds, solenoid valve assembly, venturi nozzles, and clean gas outlet. Features a liftable or bolted top cover for bag installation and maintenance access. The pulse controller and wiring are housed in a weatherproof panel mounted on or adjacent to this section.
• Middle filter chamber — the primary filtration zone, containing the perforated tube sheet, filter bags and cages, and gas distribution baffles. Side-mounted access doors (hinged or bolted) allow internal inspection and bag replacement. Housing walls are fabricated from steel plate to thickness specified for the operating pressure and structural loads.
• Lower collection hopper — receives dislodged dust from the cleaning cycle. Hopper geometry is calculated to ensure free flow of the specific dust type — steep-sided for cohesive dusts, shallower for free-flowing materials. Fitted with discharge valve (rotary unloader, slide gate, or screw conveyor connection) and, where specified, hopper heaters or vibrators for difficult-discharging dusts.
Filter bags and bag cages are produced in a dedicated, controlled area of our facility, separate from metal fabrication. This separation prevents contamination of the filter media by welding fumes and metal particles — particularly important for pharmaceutical and food-grade applications. Filter bags are cut, sewn, and finished to precise dimensional tolerances. Each bag is inspected for seam integrity, correct dimensions, and fitting type before being packaged or assembled into the unit. Bag cages are formed from wire rod or perforated sheet, welded at intersections, and dimensionally checked before fitting.
The pulse-jet cleaning system is assembled and tested as a complete sub-assembly before integration into the finished unit. Solenoid valves are fitted to the compressed air manifold, wired to the pulse controller, and individually cycled at rated pressure to confirm correct operation of each valve. The pulse controller is programmed with the initial recommended settings for the specific unit configuration and dust type, and the settings are documented in the commissioning guide supplied with the equipment.
FROM ORDER TO DELIVERY
The following table maps every stage of our production process — from initial engineering review through to final packaging and despatch. Every stage has defined quality checkpoints. No unit proceeds to the next stage until the current stage has been signed off by the responsible production supervisor or QC inspector.
Step | Stage | What Happens |
01 | Engineering & Design | Customer process data reviewed; gas volume, temperature, dust type, and emission target analysed. Equipment type and size selected. General arrangement and foundation drawings produced. Custom specifications confirmed with customer before production begins. |
02 | Material Procurement & Incoming Inspection | Steel plate, sections, filter media, electrical components, and fasteners sourced from approved suppliers. All incoming materials inspected against specification before entering the production floor. Non-conforming materials rejected and returned. |
03 | Steel Fabrication | Housing panels, hoppers, inlet and outlet plenums, and structural frames cut to precise dimensions using CNC plasma and laser cutting equipment. Sheet metal formed to specified profiles using CNC press brakes. Dimensional checks at completion of each cut and formed component. |

CUSTOM ENGINEERING CAPABILITY
A significant proportion of the dust collectors we produce are to non-standard or fully bespoke specifications. Our production capability is deliberately configured for flexibility — CNC cutting and forming equipment allows us to change dimensions without re-tooling, and our engineering team handles custom design as a routine part of project management, not as a special exception.
• Non-standard housing dimensions — width, depth, height, and bag count configured for specific site constraints or performance requirements
• Special inlet and outlet configurations — elevated inlets, side inlets, multi-inlet manifolds, low-profile outlet arrangements
• Stainless steel or alloy construction — for corrosive, hygroscopic, or high-purity applications in chemical, food, and pharmaceutical industries
• Explosion relief panels — designed and positioned to meet explosion protection requirements for combustible dust applications
• Integrated structural frames and walkways — for elevated installation or where the dust collector also supports associated ductwork or equipment
• Insulated and heat-traced housings — for applications where gas temperature must be maintained above the dew point throughout the system
• Divided filter chambers — allowing individual rows to be isolated for offline bag replacement without full system shutdown
• Special surface treatments — hot-dip galvanising, epoxy lining, or specialist coatings for aggressive outdoor or chemical environments
If your project requires something not listed above, contact our engineering team. We have designed and built dust collectors for some genuinely unusual applications — unusual inlet conditions, extreme temperatures, corrosive atmospheres, and highly constrained installation spaces. If it is physically possible to build, we can typically find a way to make it.
