Accelerate your filter design with rapid prototyping for custom filters

Prototyping is a core part of our custom design process. Ideas on paper don’t reveal how a filter will actually perform, so we build units to your specs—often within days—ready to test fit, function, and performance before production.

Prototype Development: Prove it before you scale it

Delays eat budgets. Prototyping locks in performance early, so OEMs can launch on time and on spec without the risk of late-stage redesigns.

Reduce risk where it matters

Every filter design has unknowns. Prototyping finds them before they become problems, cutting costs, rework, and frustration later on.

Keep compliance moving

Industry standards don’t wait. Filter prototype testing gives you the data regulators demand—FDA, ISO, and beyond—so approvals come faster and products move forward.

Validate for the real world

Lab results are only part of the story. Prototyping lets you see how your filter performs in actual conditions—on equipment, in environments, in use.

A rapid prototyping process built to fit your filter design and development cycle

Every prototype we create is part of our custom design process. From virtual modeling to lab validation, prototyping ties directly into the same process that carries your filter through testing, compliance, and into manufacturing, so each step builds toward launch, not away from it.

Our prototyping capabilities

These are the tools that let us cut, pleat, and form filters with the same precision you’ll see at scale, perfect for prototyping filters before full production begins.

Water jets

We cut even the most intricate shapes with clean edges and tight accuracy. This method works especially well for layered or fragile media that can’t be handled by standard cutting tools.

Pleaters

From blade to mini-pleat to V-bank, our pleating lines cover every format. Each run is tuned to deliver the right balance of airflow, holding capacity, and efficiency for your design.

CNC lines

Consistency matters no matter if it's one part or one thousand. Computer Numerical Control (CNC) machining ensures every prototype matches spec and can move smoothly into production.

Plasma cutters

Our high-definition plasma cutters shape stainless, aluminum, and galvanized steel with speed and precision, producing frames and housings that mirror final production quality.

Here’s what makes Rensa different

Prototyping isn’t an afterthought here; it’s part of a full design-to-production process. With deep engineering expertise and in-house tools, we move fast, refine quickly, and get you to launch with confidence.

Build, Test, Refine—All Under One Roof

We turn ideas into working prototypes quickly, then fine-tune until you’re ready for scale.

Structured rapid prototyping

We turn ideas into working parts in days, so you can see how the filter performs before production begins.

Problem-solving engineering

Our team has seen it all. We design around the real challenges your equipment faces, not just the easy ones.

Everything connected

Design, prototyping, and manufacturing stay under one roof, which means fewer delays and cleaner handoffs.

Room to refine

Need adjustments? We run small batches and multiple iterations so performance is dialed in before scale-up.
