Lighthouse SOLAIR Particle Counters

Manufacturer information

• Lighthouse publicly presents the SOLAIR family as portable airborne particle counters with several sensitivity and flow-rate variants.
• Manufacturer material describes cleanroom reporting, data transfer and optional use with manifolds, environmental sensors and filter-scanning accessories.
• A family name alone is insufficient because flow rate, lower detection limit, channels and software expectations differ by application.

Those statements establish a technical research lane. They do not establish that GSE has authority to sell a product, that a model is available in the buyer’s territory, or that a historical accessory remains compatible. The current written quotation must identify the manufacturer, exact model, options, supplying party and quotation scope.

RFQ questions that prevent a false comparison

• Lowest particle size and channel set
• 1 CFM versus higher-flow sampling strategy
• Classification reports and electronic-record controls
• Facility-monitoring or building-automation integration
• Filter scanning, gas sampling or environmental sensors
• Calibration, battery, carrying and probe accessories

What you can expect from GSE

A useful sourcing response should distinguish the requested model from any proposed alternative, identify the configuration being quoted, state what is included and excluded, identify the seller and warranty path, and separate confirmed facts from assumptions requiring buyer approval. It should also identify any software, calibration, consumables, accessories, installation or validation services needed to make the equipment usable.

Alternative and replacement control

Similarity is not equivalency. When an exact model is unavailable or commercially ineligible, any alternative should be mapped against the buyer’s mandatory performance, interface, documentation, calibration, environmental and lifecycle requirements. GSE does not substitute a manufacturer or model merely because the category label sounds similar.

How to submit a strong request

Attach the incumbent data sheet, manual, specification, sampling plan, facility interface requirement, certificate requirement and acceptance criteria when available. State the ship-to country, quantity, required-on-site date and whether alternatives are allowed. Redact information you are not authorized to share; submitting the public RFQ form does not create an NDA.
