JENNY

JENNY is a manufacturer of stationary electric air compressors and related pneumatic equipment, with a product history dating back to the early 20th century. The brand is known for its line of reciprocating compressors, including single-stage and two-stage configurations, designed for continuous-duty industrial applications. JENNY compressors are commonly specified for fire sprinkler systems, where they maintain air pressure in dry-pipe and pre-action networks, as well as for general plant air, pneumatic controls, and process support. The product range includes tankless and tank-mounted units, with tank capacities such as 30-gallon and 120-gallon horizontal receivers, and power ratings from fractional horsepower up to 5 hp and beyond. Electrical configurations cover 120V and 240V AC, single-phase, at 60 Hz, with some models available in dual-voltage arrangements. Performance specifications include flow rates from 3.8 cfm to 35 cfm and pressure ratings up to 175 psi, depending on model and application. Build characteristics include cast-iron cylinder construction, pressure safety valves, pressure gauges, and initial oil fill for commissioning. 3G Electric supplies JENNY air compressors and pneumatics as part of its industrial equipment catalog, offering datasheets, technical specifications, and logistics support for buyers specifying compressors for fire protection, manufacturing, and maintenance operations. The catalog includes duplex stationary electric air compressors, fire sprinkler stationary electric air compressors, and related accessories. 3G Electric serves plant engineers, maintenance managers, and procurement specialists who require documented performance data and consistent supply for replacement or new installations. The JENNY line is positioned for applications where reliable air pressure maintenance is critical, such as dry-pipe fire sprinkler systems that require a continuous air supply to hold back water until a fire condition triggers the valve. In these systems, compressor sizing is determined by system volume, required pressure, and allowable leakage rates, making the range of flow and pressure options relevant for specifiers. For general industrial use, JENNY compressors support pneumatic tools, actuators, and control systems where a stationary air source is needed. The two-stage duplex configuration provides redundancy and capacity for larger demands, while single-stage tankless models suit space-constrained or point-of-use installations. 3G Electric maintains a catalog of JENNY SKUs with manufacturer part numbers, electrical specifications, and physical dimensions to assist with selection and cross-referencing. The company provides global shipping and documentation support, enabling buyers to integrate JENNY equipment into projects across different regions. Technical resources include product summaries and specification tables that list AC voltage, stage count, tank size, cfm, and psi ratings. This information supports engineers in verifying compatibility with existing systems and in preparing submittals for approval. 3G Electric does not manufacture JENNY products; it distributes them as part of a broader portfolio of industrial burners, pumps, gas controls, and related equipment. The JENNY line complements other product families by addressing compressed-air requirements in fire protection and industrial processes. For procurement, 3G Electric offers quotation support and logistics coordination, with the ability to ship to international destinations. The catalog includes both current and legacy part numbers, which can assist in replacement planning for existing installations. Overall, the JENNY brand represents a focused range of stationary electric air compressors with documented performance characteristics, available through 3G Electric for global industrial buyers.

Frequently asked questions

Common questions about JENNY from 3G Electric.

What are the electrical requirements for JENNY fire sprinkler air compressors?

JENNY fire sprinkler air compressors are available in 120V AC and 240V AC, single-phase, 60 Hz configurations. Some models, such as the tankless 0.5 hp unit (MPN F12S-BS-115/1-ACGF), are dual-voltage capable. The specific voltage and amperage draw depend on the model and horsepower. For example, the 2 hp tankless model (K2S-BS-115/1ACGK) operates on 120V AC, while the 2 hp horizontal 30-gallon model (K2S-30UMS-115/1) uses 240V AC. Always verify the nameplate data and consult the datasheet for the exact model to ensure compatibility with the available power supply.

How do I select a JENNY air compressor for a dry-pipe fire sprinkler system?

Selection depends on system volume, required air pressure, and allowable leakage. JENNY offers single-stage compressors with flow rates from 3.8 cfm to 12.4 cfm at 40 psi, in tankless or tank-mounted configurations. Tankless models are used where space is limited or when the system itself provides air storage. Tank-mounted models with 30-gallon receivers can reduce compressor cycling. For larger systems, duplex configurations such as the 5 hp, 120-gallon unit (2W5B-120-230/1) provide redundancy and higher capacity. Consult the system designer to determine the required cfm and pressure, and match to a JENNY model with appropriate ratings.

What is the difference between single-stage and two-stage JENNY air compressors?

Single-stage JENNY compressors compress air in one cylinder stroke, typically used for pressures up to 40 psi in fire sprinkler service or higher pressures in some general industrial models. Two-stage compressors, such as the 5 hp duplex unit (2W5B-120-230/1), compress air in two stages, which can achieve higher pressures (up to 175 psi) and improved efficiency for continuous-duty applications. Two-stage units are often chosen for higher pressure requirements or when a smaller tank is desired for a given capacity. The choice depends on the required discharge pressure, flow rate, and duty cycle.

Are JENNY air compressors suitable for continuous duty?

JENNY stationary electric air compressors are designed for industrial applications, including continuous-duty operation in fire sprinkler systems where they maintain air pressure. Models such as the duplex stationary electric air compressor (5 hp, 2-stage, 120-gallon) are built for demanding cycles. However, duty cycle ratings depend on the specific model and application. For continuous duty, ensure the compressor is rated for 100% duty cycle and that maintenance intervals are followed. Fire sprinkler compressors typically run intermittently to maintain pressure, but they must be capable of starting under load and operating reliably over long periods.

What maintenance items are included with JENNY fire sprinkler air compressors?

JENNY fire sprinkler air compressors typically include an initial fill of compressor oil for commissioning. Some models also include a pressure safety valve and pressure gauge. For ongoing maintenance, refer to the manufacturer's manual for oil change intervals, filter replacement, and valve inspection. Common maintenance parts include air filters, oil, and pressure switches. 3G Electric can provide datasheets and part numbers to assist with identifying replacement components. Always follow the manufacturer's recommendations for maintenance schedules to ensure reliable operation and preserve warranty coverage.

Can JENNY air compressors be used for general industrial air supply?

Yes, JENNY air compressors are used in general industrial applications such as pneumatic tools, actuators, and control systems. The range includes single-stage and two-stage models with various tank sizes and power ratings. For example, the 5 hp duplex unit delivers 35 cfm at 175 psi, suitable for larger shops. Smaller tankless models can supply point-of-use air. When selecting for general industrial use, consider required cfm, pressure, duty cycle, and available power. JENNY compressors are not limited to fire sprinkler service, but the fire sprinkler models are specifically configured for that application and may have different pressure settings.
