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

Picture too small or installation distance not enough? A different lens can solve it. FA106 is compatible with 2 Hualu projector models — see the list below.

Where It Works: List of 2 Compatible Models (with Specifications)

Below are the verified compatible models for FA106 (Hualu projectors), 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 nameplate/manual for accuracy); lens compatibility is based on the chassis interface and optical structure. For models not listed, contact Zorsika technical support for confirmation.

Frequently Asked Questions

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

A: First confirm the model's lens interface and optical axis position, then select a lens with the appropriate throw ratio based on your actual installation distance. If unsure, send your installation distance and screen size to Zorsika technical support and we'll help you choose.

Q: My projector isn't in the list of 2 models above — can I use FA106?

A: The list covers verified models, but it doesn't represent all possibilities. Engineering projectors of the same brand and generation often share the same lens interface. For a more reliable answer, send a photo of the model nameplate and the original lens to Zorsika technical support for confirmation.

Q: Can this lens replace the original one?

A: The lens is the core of the projector's optical path and directly determines clarity and color. Zorsika lenses (model numbers as shown in the specification table above) are benchmarked item by item against the original optical parameters (focal length, throw ratio, lens group), with consistent lens coating processes, delivering sharp imaging with no soft edges. Ordinary replacement lenses often use standard glass elements with insufficient coating layers, resulting in brightness loss and color shift that are immediately visible. For engineering and exhibition scenarios, Zorsika is the recommended choice.

Q: Why choose Zorsika instead of the original manufacturer?

A: Zorsika lenses are produced according to the original optical drawings, with the lens group, coatings, and throw ratio benchmarked item by item, and each unit undergoes resolution testing before leaving the factory. Compared to the original manufacturer, lead times are shorter and overall value is better; compared to other replacement lenses, optical quality is backed by data.

Q: How long is the lens warranty?

A: All Zorsika projector lenses come with a 12-month warranty. For normal use and non-human-caused damage (such as impact, water damage, or unauthorized disassembly), you can contact after-sales service directly. The warranty period is based on the date on the shipping document.

Same Specifications — Why We Recommend Zorsika

Zorsika offers an original-spec replacement lens for FA106, with key parameters benchmarked item by item against the original, and supports bulk project procurement and supply.

Zorsika's same-spec replacement model is compatible with Hualu HL-GU21K, HL-GU18K, and other models — 2 in total. Enter FA106 in the Zorsika official website query system to see the complete model compatibility list.

• Optical Benchmarking: Focal length, throw ratio, and lens group matched to original parameters
• Resolution Testing: Each unit tested before shipment, with MTF data available
• Coating Process: Lens coatings at the same grade as the original, reducing light loss
• Stable Supply: Supports bulk procurement and project supply

In one sentence: The lens is the optical core — don't gamble on picture quality to save a few dollars. Zorsika projector lenses are produced according to original drawings and offer better overall value.

Note: Actual imaging performance is affected by the projector's condition and installation environment. Before bulk procurement, we recommend ordering 1 unit for testing.

What to Watch Out for When Replacing a Lens

• Power off before replacing the lens: Before removing or installing the lens, be sure to shut down and wait for the cooling fan to stop, to avoid damaging the interface while powered on.
• Don't touch the lens elements: Fingerprints and oil will directly affect image quality. Hold the lens by the barrel, not the glass. If there's dust, use an air blower to gently blow it off — don't wipe with a dry cloth.
• Focus first, then tighten: After installing properly, test the focus first, then tighten the fixing screws to avoid loosening over time that causes image drift.
• Keep the interface clean: Dust buildup on the mount and contacts can cause poor contact. Cleaning them while replacing the lens is a safer practice.
