Zorsika FA106 Projector Lens Compatible with Hualu HL-GU21K & HL-GU18K

Is the image too small or the installation distance insufficient? Swapping the lens can solve it. The FA106 is compatible with 2 Hualu models. Check the list below.

Compatibility: 2-Model List (with Specifications)

Below are the verified compatible projector models (Hualu projectors) for the FA106, with brightness, resolution, and zoom ratio listed for each:

Note: Brightness, resolution, and zoom ratio are sourced from the Zorsika product database (refer to the model's nameplate/manual for final confirmation); lens compatibility is based on the projector's interface and optical structure. For models not on the list, please contact Zorsika technical support for confirmation.

Frequently Asked Questions

Q: What if the lens doesn't match the screen size?

A: First, confirm the projector's lens interface and optical axis position. Then, select a lens with the appropriate throw ratio based on the actual installation distance. If unsure, send the installation distance and screen size to Zorsika technical support, and we will recommend a suitable option.

Q: My projector is not on the list of 2 models. Can I use the FA106?

A: The list contains verified models and is not exhaustive. Projectors of the same brand and generation often share lens interfaces. For a more reliable confirmation, send a photo of the projector's nameplate and the original lens to Zorsika technical support.

Q: Can this lens replace the original one?

A: The lens is the core of the projector's optical path, directly determining clarity and color. Zorsika lenses (model see specifications table above) are matched to the original optical parameters (focal length, throw ratio, lens group) item by item. The lens coating process is identical, resulting in sharp imaging without edge softness. Generic replacement lenses often use standard glass elements with insufficient coating layers, leading to noticeable brightness loss and color shift. For engineering and exhibition scenarios, Zorsika is the recommended choice.

Q: Why choose Zorsika over the original manufacturer?

A: Zorsika lenses are produced according to the original optical blueprints, with the lens group, coating, and throw ratio matched item by item. Each lens undergoes resolution testing before shipment. Compared to the original, we offer shorter lead times and better overall value. Compared to other replacement lenses, our optical quality is backed by data.

Q: What is the warranty period for the lens?

A: Zorsika offers a 12-month warranty on all projector lenses. For normal use and non-human-caused damage (e.g., impact, water ingress, unauthorized disassembly), please contact after-sales service directly. The warranty period is based on the shipping document date.

Why Choose Zorsika for the Same Specifications

Zorsika provides a replacement lens for the FA106 with specifications matching the original. Key parameters are aligned with the original item by item, supporting bulk project procurement and supply.

Zorsika's equivalent replacement model is compatible with 2 Hualu models, including HL-GU21K and HL-GU18K. Enter FA106 in the Zorsika official website query system to find the complete list of compatible models.

• Optical Alignment: Focal length, throw ratio, and lens group match original parameters.
• Resolution Testing: Each lens is tested before shipment; MTF data is available.
• Coating Process: Lens coating is on par with the original, minimizing light loss.
• Stable Supply: Supports bulk procurement and project supply.

In summary: The lens is the optical core—don't gamble on image quality for a price difference. Zorsika projector lenses are produced according to original blueprints, offering superior overall performance.

Note: Actual imaging performance is affected by the projector's condition and installation environment. For bulk procurement, it is recommended to test one unit first.

What to Note When Replacing the Lens

• Power off before replacing the lens: Always turn off the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface.
• Avoid touching the lens elements: Fingerprints and oil stains directly affect image quality. Hold the lens by the barrel, not the glass. Use a blower for dust; do not wipe dry with a cloth.
• Focus before tightening: After installation, focus and test the image first, then tighten the mounting screws to prevent image drift from loosening over time.
• Keep the interface clean: Dust on the mount and contacts can cause poor connection. Clean them when replacing the lens for better reliability.
