Custom made filters with special sizes
If your application requires filters in special sizes or shapes, we can produce custom filters for your equipment requirements upon request - whether you need a single filter or a larger batch.
Technical specifications
- Thickness: Standard thickness is 1.1mm. Custom thicknesses are only possible for larger quantities.
- Shapes: Circular filters are straightforward to produce, but we can also manufacture square, rectangular, hexagonal, or other complex shapes.
- Sizes:
Minimum diameter: 20mm
Maximum diameter: Varies by filter type (see below).
- Tolerance: The filters are cut to the requested diameter with a tolerance of +0.0mm / -0.2mm.
Custom transmission curves
- For large quantities, we can produce filters with custom transmission curves. To ensure attractive pricing, we recommend ordering around 50 filters with a 50mm diameter or an equivalent surface area of 0.2m2.
Ordering
- Custom sizes and special orders are not available through our dealers. Please contact us directly for a quote and to discuss your specific needs.
