About Us

Design Software Capabilities

Dauji engineering is an end to end solution provider for all your filter component requirements. From basic designing & modelling of the component (reverse engineered from component sample, if necessary) to manufacture, inspection, export packing & customs clearance to door delivery at your factory, we take care of it all.

At Dauji Engineering, precision and performance are foremost to our company. To meet the highest design and engineering standards, we rely on industry-leading software tools — AutoCAD and SolidWorks — to develop & model every component we manufacture

AutoCAD – 2D Drafting

We use AutoCAD for detailed 2D drawings of filtration components and systems, including:

  • Layouts for filter housings, end caps, and gaskets
  • Accurate dimensional drawings for fabrication
  • Documentation for manufacturing

AutoCAD helps us deliver schematics that ensure compatibility and ease of communication with OEMs and fabricators.

SolidWorks – 3D Modeling

Our team uses SolidWorks to design complex filter components.

  • 3D part modeling for filter cages, end caps, and parts
  • Stress testing for critical components
  • Exploded views and photorealistic renders for client visualization

Material Selection and Application Focus
Our filter components are crafted from a range of durable materials including plastic, galvanized steel, stainless steel, and aluminium, suitable for diverse industrial environments. Threaded flanges are offered in sizes RD60, RD72, RD73, RD100, and RD200.
Primarily focused on air and dust filtration, we use materials like polyester (our most popular), cellulose blends, nano-layered polyester, and flame-retardant options. For environments with explosive dust, our antistatic versions are essential. Additionally, all polyester filters can be treated with antistatic, PTFE coating, or PTFE membrane.
