Based on the search results, there appears to be significant confusion regarding the GENERAL FILTER 2A-700A. The information points to two distinct products under the same model number: a fuel oil filter cartridge for heating systems and a high-efficiency industrial air filtration system. The specifications for these two products are entirely different and incompatible.
The following table contrasts the primary specifications reported for each type of product to highlight the discrepancies.
🔧 Key Details for the Fuel Oil Filter Interpretation
The information supporting the 2A-700A as a fuel oil filter is more consistent and detailed across multiple retail and parts supplier sources .
Replacement and Compatibility: This cartridge is listed as a direct replacement for model 2A-700A and is also sold under part number 2A710 . It is designed to fit a variety of filter housings from different brands, including Unifilter, Sid Harvey, and Autoflo .
Design Features: The cartridge uses a 10-micron wool felt material with a center core bond design, which prevents the filter media from migrating and ensures consistent performance .
Maintenance: The primary maintenance involves replacing the cartridge, which is a straightforward process designed to minimize downtime .
💡 Industrial Air Filter Interpretation
The description of the 2A-700A as an industrial air filter, while present in the search results, contains internal contradictions (e.g., being described for both “fluid” and “air” purification) and originates from sources with lower authority . The specifications provided, such as HEPA efficiency and ISO certifications, are typical for high-end air filters but do not align with the physical dimensions or application of a fuel oil cartridge .
✅ Conclusion and Recommendation
The evidence strongly suggests that the GENERAL FILTER 2A-700A is, in fact, a fuel oil filter cartridge for heating systems. The specifications for the industrial air filter likely result from a model number mix-up or inaccurate product listings.
Before making a purchase, it is crucial to confirm the exact product you need.
If you are maintaining an oil-fired burner or boiler, the fuel filter cartridge description is almost certainly correct. Verify the specifications like GPH rating and connection size (e.g., 3/8″ NPT) against your existing equipment .
If you require an industrial air filtration system, you should contact a specialist supplier directly with the model number and your application details to avoid receiving an incorrect product.
